You’re an absolute legend!... sometimes I just listen to you like a bedtime story.
With a classic and a disco 1 there’s always plenty to fix too.
Cheers for all your help.
Thanks for listening
There was some quite useful info here, that helped me when replacing the servo on my 6x6 land rover.
Many thanks for the video.
Great to hear!
4:14 “I can’t get it in”. So said the Bishop to the nun. Good one mate. Another ‘straightforward’ job on that safety certificated vehicle. Oh well; it buys you a loaf of bread. 🙈👍🏻😂
I like the way the complete new Servo Assembly moved when you were trying to get a decent pedal, I wouldn't have even driven it, keep up the good work, always informative with a mere hint of humour,
Bulkhead is totally rotten
@@BritannicaRestorations Ghanaian Air Conditioning?
Mike you hero. Did the job today and the angled needle nose pliers are a must. Fiddley job for access but for someone who only plays at diy mechanics like me its manageable 👍
Keep the Cap's on! Dust flying about, Dirt etc, even rain here in Scotland, surprise surprise!! Keep up the good work Mike.
Thanks, you too!
Hi Mike 👏 thanks again for this update 👍👍👍🇬🇧🇬🇧🇬🇧
My pleasure!!
Brilliant as always Mike. 😊
Glad you enjoyed it
Me and my mom had a good laugh at that brake check at the end.👍
Lol!
Mike, I believe I saw some flat spotted tyres after that brake test .... time to return to the pits and get new ones ......😀
A job well done 👍👍👍👍
Many many thanks
Pro-tip: always put a smear of coppaslip/anti-seize around the ends of brake pipes after you work on them - being careful not to get any INSIDE the pipes.
Everybody knows that brake *fittings* can be an arse to remove but often the fittings get rust-welded to the ends of the pipes and you're forced to mangle the pipes as you unscrew the fittings.
A dab of coppaslip will prevent this and future-you will thank you for doing it.
Coincidentally, I fitted a new master-cylinder to a 110 last weekend (amongst other brake repairs) for the MOT and BOTH the fittings on the top of the master-cylinder were rusted to the pipes, which resulted in the pipes shearing as I unscrewed the fittings... and forced me to replace the bloody pipes too, even though they were in decent condition.
Even if you're using cunifer pipe, when the fittings go rusty it can cause them to seize onto the pipe so coppaslip is still a good idea.
Also, you know that when you did that brake-test, the rear wheels were still turning, right? ;-)
I agree rusted unions are a real pain. Red rubber grease is waterproof and brake fluid friendly so I smear that on my unions. No need to worry if a dob of it gets inside the pipe.
You can get brass unions as well. I would be interested in Mikes view on using them. I assume they work well but manufacturers don't fit them due to cost?
It has drum brakes and there is a pressure reducing valve in line - you do not want the rears to lock solid as it is light on the back end -- locked rears can spin the truck on wet roads ( go on ask me how I know that! lol!)
Yes brass fittings are good, but hard to find - some of the pre made kits have them
From experience, I only see them on Cunifer lines as there is less torque needed to seal the joint - on steel lines I think there could be a tendency to strip the threads
@@BritannicaRestorations Car Builder Solutions (UK based) have a good selection of brass unions, both metric and imperial. They also do stainless steel, which I guess would work with steel lines.
Or AutoMec , again UK though so shipping costs to consider but got them all round on the series as well as stainless nipples! Ooooh er misssus :D
DO it right, and do it once. Nice video Mike, as it should be done. Rob.
Even though you do this, it is like peeing against the wind!
That stop was almost worthy of a knight rider episode!:)
well, this is almost a KITT car!
lol!
@@BritannicaRestorationsyes almost!May contain parts is all it said in the construction booklet!:)
By eck Mike! Thems are turbo sport brakes!!!
Now the driver will know how a fly feels hitting a windscreen when he brakes!!!😂😂😂
Also great to see another trusty rusty bulkhead from the continent of A.
You got that right!
They've definitely used up all the new on that servo!
3:30 My rule with split pins is to always think of the poor bugger who will have to take it out next, as chances are it will be ME! Doing it right is actually easier than doing it wrong.
Agreed!
Ayup there mike my top tipette is to take the entire brake tower out and change it all out on the bench loads easier.Atb Andy.
This was not too bad - you should see the mess that is holding on the tower
OH _gosh. It remind me of my 1961 Citroen ID19. It uses DOT3 type fluid for brake and suspension and replacing any component in the circuit is nightmare and messy, It melt paint !
👍👍
The Heinz 57 type Land Rover badger Ghana 🇬🇭 special equipment. I’m truly sorry I cannot resist taking the p@ss just a little sad I know. I’m truly thankful for the humour that you have supplied me in the time of corona lemonade....ooops virus 🦠 not beer 🍺 either god bless you sir . Thanks for putting up with the cranky comments really enjoying the updates on it . Thinking of starting a charity for owners duped into the ownership of the ghastly Ghana 🇬🇭 jobbies pleased it is giving us content
*"corona lemonade"* you're of a certain age if you can remember Corona soft drinks. Remember "Every bubble passed its fizzical!" ua-cam.com/video/IcuOiGnbSmU/v-deo.html
COIcultist certainly feeling old these days
I am going to have to put my prices up soon to stop all these vehicles coming here for repairs - it is getting bad now and very expensive for owners who think they are catting a good truck, only to find it is a money pit
Britannica Restorations Ltd you do seem to be rather generous with your time feeling sorry I feel for these people. They really need to learn about false economy. I’m pretty sure that in Ghana 🇬🇭 when even their best bodgers can’t bodge any further with the with their amazing resources they then are really ready for the cash in export business. Also I must not forget the telephone scams of fake tribal kings 👑 who need assistance with moving gold. I sure you could certainly come up with some famous sayings such as one born every minute
Flatten the curve the other waý. Any wheel wobbling now?
Great informations as usual.
Not that I know of
How many takes did the brake test take? Interesting video as always.
One take!
Excellent feature. I have Disco 1 with 110 calipers. Do you know if its easy to fit Def 110 master cylinder and servo?
I have a feeling the stud holes are different on the Defender servo (4 stud fixing)
The Disco servo and master should cope but I see the Defender master has a different part number LR013018
Not too sure on this modification
@@BritannicaRestorations thank you for the quick reply. Disco master copes now. I may be fitting Disco 4 pot front calipers to the rear (with a bracket from Redwinch/Bowler) so will see if it has capacity then. It's the usual greater vehicle weight, bigger tyres, brakes inadequate issue.
Hello mate, got a 300tdi 90 that has low braking ( below the pass test ) on the rear axle apparently... Every single part on the system in new beside the rear brake valve. Please help as I can't put the car on the road and I am getting desperate. Much appreciate it.
Guess what - it will be the brake valve! Quite common for them to draw air in - not sure if an over haul kit exists now but they are only O rings - check out the MG etc sites as they have the same setup
OR buy a new one - £££$$$$£££!
@@BritannicaRestorations Again you are saving my as*. Thanks from Eastern Europe.
Did you receive a filter and o-ring with your TRW master cylinder?
Videos are very helpful.
Thank you.
Got the O ring but no filter
@@BritannicaRestorations Thank you and Happy New Year
I just love this Landy - just a couple of days ago you pushed it off the lot and waved bye bye to the owner (after he dropped $4K - if he was lucky) - certainly a fun conversation he had with his spouse - then the next day his honey wants a ride in the new POS - but he has to inform her there are no brakes - but don't worry wife Mike will take care of it - then a short time later the wife is demanding to see the receipt for the new work - $1,200 she screams ! But rest assured this will be the last of the repairs - LOL
Pretty much like this!
Just done a master cylinder swap on a 300tdi, bad brakes, swapped pads and rear calipers as they were seized, discs ain't the best either, pedal gets sucked down on startup so hoping the new discs will sort it without a servo swap.
I think you'll find that's an internal booster problem.
@@gazzafloss I fear you maybe right.
Agreed - never seen that before!
@@BritannicaRestorations Thought it was the M/C cos pedal was spongy even after bleeding, checked all hoses and all good. Vacuum pump creates decent vacuum and pedal is sucked down on startup, at least its only £45 for a new servo (one advantage of the UK and having a land rover supermarket down the road) discs are worn very unevenly anyway so could do with replacing, just a bit of a faf to fit.
do you ever have to adjust the servo push rod length?
NO! You should never have to adjust it - if you do you can lock the brakes when they get warm an the fluid expands
I was going to say , let’s open the old one up and see how they work, but then again I don’t think there’s much to them
I was thinking the same!
where does the servo vacuum hose from the servo connect to please?
On a diesel it goes to the vacuum pump on the engine
Hello mike.I have a question regarding to land rover discovery 1 brake master cylinder.can a 200tdi (NTC4991)discovery brake master cylinder fit into a 300tdi(STC1285)discovery ? Non-Abs model they have only 2 pipes to front and rear caliper
Looking at the existing part they are very similar can it be done ?
I really have no idea as I have never seen a 200Tdi discovery for over 10 years! Sometimes best to play safe and fit the correct part!
Hi Mike, is there a way to test the servo when they are off the car. I've always found that my brake pedal slowly goes to the floor, then I have to re-press it to get the brake. Thanks
Sounds like it has a leak
@@BritannicaRestorations umm, repairable or replacement?
hello mike. great video.it does not surprise me that there are clowns out there that will bodge repairs to a brake system.its quite frightening really. its called atheur daley land rover repairs.
How did this get through the inspection station door?
Good day sir i baught a new servo vacume brake valve but my new ones diameter are bigger than the old one though the valve are looking the same can one put a rubber pioe on or mus i try and buy a bigger diameter brake valve vacume booster pipe i tried boiling water to soften it butt it refuse to strech
You didn't say which vehicle you have but if the VIN is to HA701009 then the part is 18G8953L, after it is STC493
@@BritannicaRestorations its a defender td5 2002 i send you an email sir with my vin number thnak you
My 110's brake pads always finished from inside once a year (i am a daily user). Is it about brake master cylinder?
Hard to say - The M/c should be in a neutral position - no pressure - not unless someone has fannied about with the servo and adjusted the pin that pushes on the M/c piston
@@BritannicaRestorations thanks for care
who did the inspection on that blind pew?
We have the best inspectors money can buy!
Guys i am having problems with my Landy brakes. My front disc brakes are not releasing when i take my foot off the pedal. I have put brand new calipers and new hoses on both wheels. The brakes get so tight after about 10 minutes driving, that i have to stop to let the discs cool down before driving off again. There are no kinks in the hoses at all. Could there be a master cylinder problem?
Appreciate any feed back please. Landy is almost 30 yrs old, and master cylinder is the original one.
Thanks in advance
Tony
It could be the servo has been played with and the push rod adjusted too much - or a bad master - the fluid is not returning to the master cylinder
@@BritannicaRestorations Thank you very much for prompt reply. I will check the survo and master cylinder . Thanks again.
Why is it a LHD model
Mike you shouldn't have said it is a straight forward job at the start of video,I think you must of forgot where the defender came from
Would you or have you used a bearmach booster? Over the TRW?
Not sure of the Bearmach ones - but the TRW are the OEM supplied
@@BritannicaRestorations what exactly does the second gasket on the vac pump achieve mate?
Seems to reduce stress on the pump mechanism
@@BritannicaRestorations does it create any lose of vacuum? Does it actually prolong the life of the pump?
Is this job any more difficult on a RHD vehicle?
Not really
If checker-plate is so good, why don't they build land rovers out of it completely?
many of them are over here....
Another part to lob over next door's fence...........
His place is looking like a real junk yard - I think I will report him!
Thanks Mike, I liked the comment, "just in case it needs to come out again." Your not suggesting that footwell needs replacing are you?
Years left in that, well years in a hot climate. OK, months.
I have a feeling that needs replacing!
What happens when the driver emergency brakes and the rot on that firewall let's the pedal box move to the 'Twilight Zone", like I said before, best vehicle inspectors money can buy...
I agree!
Just a bloke who hasn't ever done a brake master cylinder, only brake calipers and clutch master and slave cylinders.
I am/was of the belief that all succeeding DOT brake fluids could be used on and mixed with a former type but had superior properties. Why would you use an older spec?
Can be used in a fully cleaned system I think, but mixed no...
@@gazzafloss As far as I'm aware you only need to uprate a fluid i.e. from DOT 3 to 4 to 5.1 but specifically not DOT 5 which is a completely different silicone fluid.
This would be bourne out by several websites. The problem is I used to moderate and write for a folding camper website and I wrote a piece on UK towing regulations. The amount of sites that got the law wrong including at one point Gov UK were unbelievable. Alas, Gov UK didn't provide a historical page to show its error. I have very little belief in websites. Look at these below:
www.brakeandfrontend.com/brake-fluid-dot-3-4-5-5-1-faq/
rxmechanic.com/dot-3-vs-dot-4-vs-dot-5/
epicbleedsolutions.com/blogs/faq/whats-the-difference-between-dot-4-and-dot-5-1-brake-fluid#
haynes.com/en-us/tips-tutorials/brake-fluid-types-explained
Some of whom agree with me some don't two of whom list the dry boiling point of DOT3 fluid as 205 deg C or 250 deg C. One says "DOT 3 brake fluids are a petroleum/non-mineral based, non-silicone, and fully synthetic brake fluid designed for use in a wide range of clutch and brake applications." How can it be petroleum based yet non-mineral? Surely it can't be fully synthetic either if petroleum based? Once upon a time I might have believed Haynes who tell you can't mix any fluid but Haynes appear more interested in selling crap books rather than car mechanics and let's face it even many years ago we all knew. Assembly wasn't just a simple reversal of the above procedure!
A quick search on UK eBay gives a litre of Comma Dot 3 £8.60, a litre of Dot 4 £7.99. I can't see the advantage of using Dot 3 unless Canadian or wholesale prices are different from UK.
You can't mix Dot 5 with any other, but Dot 4 can be used instead/mixed with Dot 3.
DOT3 is the most popular here for disc front, drum rear applications and sold in gallons but DOT4 is sold in litres, and as 80% of the old trucks I get here are over 25 years old DOT3 is ok for my use - there is only 10c difference in dry boiling point as far as I am aware - if they sold it in gallons I would buy it
I agree do not mix DOT3/4 with 5
press brake hard and bulk head moves forwaard 3 inch.press and prey
It's ripe!
Very good squadron leader yu rev head ..🤣😂😎pip pips and carryon
Lease it stops without using 2 feet on the pedal!
@@BritannicaRestorations i cant find the video you made about using a electric vacuum pump from a volvo for servo
Mike, get Farage over to investigate these clowns who carry out these so called vehicle inspections, he's doing wonders highlighting these day trippers who are heading over to Blighty from France, apparently it's a free for all, would you believe it once you land on their should I say our shaw's, a nice four star hotel awaits.
What could possibly go wrong.
Hmm - lockdown for some but not for others
