Thank you for this video, I put the round thing in the hole with out the plastic piece going in first and got it stuck, I wasn't sure how it reassembled until now. You saved me so much head ache and time! Thank you!
On my 93 Silverado 3/4 ton, I had a bad leak, so I tore it out, disassembled, and rebuilt with a generic (EBAY) rebuild gasket kit. It leaked. Tore that out, and realized somewhere along the tear out, and rebuilding of the original, that the accumulator became loose. That means death to the unit, and you can’t rebuild it at home. And in my application, it’s a DISCONTINUED PART ! Went to Autozone and ordered a Duralast remanufactured unit. Installed it, and it leaked. Tore that one out, brought it back to Autozone, and they ordered another one for me. Installed that one, and it leaked. I DID NOT RETURN THE SECOND UNIT FOR A REPLACEMENT. And this is my suggestion to anyone doing this rebuild. First and foremost, if the accumulator feels loose, or wobbles around and isn’t tight, your unit is toast, and you have to go with a rebuilt. Second, order a rebuilt unit from Autozone or your local parts store. Why ? For the warranty, and it’s local. I’m so glad I went that route. As for the “rebuilt unit”, it probably came from A-1 Cardone if you got it from the parts store, and that basically means it’s pretty much just what you took out of your vehicle, garbage. What did I do ? I tore out the second unit from Autozone that leaked, and disassembled as in this video. Now listen carefully here…I did not use a GENERIC REBUILD KIT FROM EBAY this time around !!!! I found a genuine GM rebuild kit on EBAY (new/old stock) and ordered that. Disassembled the unit and rebuilt it just as I did the original unit in the truck, and NO LEAKS !! The aftermarket generic gaskets are a very big “hit and miss”. These are rubber sealing rings with a VERY SPECIFIC SHAPE to them. If the tolerances are off, by even a little bit, it’s going to leak. Good luck my friends !
Can you advise? I am rebiilding a school bus witha chevy p30 chassis and the first thing you see when i ooen the hood is the hydroboost and master cylinder on the firewall- so i want to chrome the whole thing. The chrome shop wants onlu the external housings that need to be chromed. The whole proces will take months with back time.and shipping so the bus needs all new components anyway id buy a remanufactured boost and master and disassemble it myself and send the parts out and reasemble the chrome housing when it gets back chromed. Heres the question, how do i remove the pressure canister or does that even need to be removed ? Does it hold pressure? Is it under pressue like a nitrogen ball from a bmw brake system or is theee nothing in that canister and it should be chromed as one piece with the housing? Thats my question.
i dont understand why everyone takes the whole thing outta their cars you can leave the part thats attached to the firewall and save you all kinds of trouble by doing so
Do you think the master cylinder will cause all 4 brakes to slightly drag? I can release each one when I open the bleeder screw. Once I drive it for about 3-7 minutes it starts back dragging. I say slightly dragging because I can jack up the truck and turn them by hand with a lot of force. No leaks on the master cylinder or hydro boost. I’ve greased slider pins, bleeding the brakes 3 times, topped off the fluid on both power steering and brake fluid. Power steering is making the whining noise. Pedal is hard not soft. It’s a 2004 Suburban with hydro boost system. Please help.
Operating pressure gets to the wrong place in the brake master cylinder if all brakes are stuck, usually old brake hoses do this, but only wheel-specific sticking.
@@latexihire yes the front brakes would stick completely and then I changed the front rubber brake hoses and now it’s slightly. So you think I should change the master cylinder?
@@latexihire I’m going to released the 2 bolts on the master cylinder to see if it releases the brakes. What if it does release the brakes do I just replace the master cylinder?
The little plunger that sits on top of the little yellow cone looking thing mine does not look like that it has three little bitty holes do they face towards me and also whenever I broke my Hydro boost and have it had pressure and sprayed all over me
I just rebuilt my hydrobooster. Now when I turn the wheel the breaks go down. Any ideas where to start? I made sure two function valve is in the same way yours is. My an original one was different than the one that came in the rebuild kit. The new one is just like yours.
Ok There is probably air in the brake master cylinder, the first air out of the nipples of the brake pipes and the air off line towards - > the brake cylinders of the axles.
Could you show/explain/use a drawing of the proper dump valve assembly please. I'm doing a GM and not real sure of the proper reassembly mine fell out... (? Gasket, yellow plastic, pin and exterior end piece) not sure of the correct reassembly. I really would appreciate it sir, thank you
what all yrs does that pretain too i have a 98 gmc 3500hd i got a new replacement part and it all ready has that in it so do i still take out my old one and put in the new part even it all ready has one,,,,im curious
What about the seals on the push rod? I watched another video and the guy cut off the eye. Pulled the rod out replaced the seals. Put the rod back through the housing and welded the eye back on. He said he did this because he couldn't figure out how to remove it. There were no obvious ways of removing it. So I have been searching for a proper way to replace the seals.
The pushrod is held in place due to the end being a ball and then the metal is staked/dented to retain it. Instructions with seal kit show a pry tool to force it out. I made a version with a bearing puller and some all threaded rod. Then to reinstall you need to hold the push rod to the master cylinder side in so you can apply force and not distroy the star washer and then just hammer or press the ball end of the pedal pushrod back into place.
I didn’t take any lines off and only replaced the piston seal and the figure 8 seal. Now I turn the truck on it sucks the brake pedal down. What in the world did I do wrong?
@@latexihireI was doing the job with the unit in the truck and didn’t lock the pin into the fork but had it pushed against it instead. Ran it for 100 miles and now the brake pedal goes down when I steer so I guess I’m taking it apart for a third time
How to change the small o rings on the pedal rod without cutting a pedal rod with a grinder??? Rod is pressed in and no way to disassemble that. That's where mine is leaking. Video did not show. My truck is RAM, nearly identical part. Anyone please?
You can pay the $55 to buy the tool (J24569), or you can fabricate your own by cutting a slot for the rod into 1/4" flat stock, then welding angle iron to that about 1" from the slot, drill a hole for a drift into the angle iron centered at about the end of the rod. Now you can put the tool into a vice and use a large drift punch to quickly pry up on the rod, freeing it from the cylinder. To reassemble put a bolt/pin the size of the pedal hole in the rod, line it up on the cylinder, and give it a quick and strong smack with a hammer and it should seat itself again. If you don't put something in the hole for the brake pedal you run the risk of deforming the hole and it will be difficult/impossible to get the rod on the pedal to go through when you reinstall the hydroboost, and it's absolutely miserable to try and make that hole round again.

Thanks .. but Dedicate a video How to disassemble the connection between the brake pedal and the hydraulic booster... so that new rubber rings can be installed, to avoid leakage.

You have to cut the eyelid off and after replacing the seals weld the eyelid back on ,or cut some threads on both sides and use a coupler nut to get it together for use in the truck
That's a special fault, it shouldn't be connected to that brake master cylinder, I'm guessing some kind of linkage problem, remove the shields from the front and examine the movements of the arms. In my Van, there was a problem with the brake hoses when the brakes were left on, the old brake hoses were swollen and the pressure remained in the work cylinder.
I have one problem you can only get seals by themselves online auto shops won't sell seals and mechanics upcharge way to much I can not order online and I don't have friends that'll let me use their addy to pick up parts I'm about to use my jobs address since they want to make life difficult for no reason
The diagram shows a ball bearing between the two components of the accumulator valve (the yellow piece and the piece with the pin in it), yet your unit had NO such ball bearing.

Dude... Your detail is top friggin notch
Well done! No blathering on. Excellent camera shots. You gave me a ton of confidence I'll get it right the first time.
As a seasoned mechanic I highly recommend using a gasket sealant on that critical sealing ring but only only the lip that contacts the casting
The little yellow plastic thing was lost during disassembly.. life saver for your camera shots
Did it have a small ball bearing in it

The seals will slide over the rod and work them down. With old gaskets still in place get them close then cut the old ones off.
