    @6364CadillacChapter. Hi there 6364, Great video to begin with. First you remove the Cap off of the Reservoir from the top of the Master Cylinder. Then bleed the Caliper. I've had to Bleed Calipers before by myself. As usual I always watch a video just in case I forgot to get out both of my Brake-Kits. lol Wouldn't be the first time....
    Edit: ***I decided to buy a Caliper Spread Tool because when I was spreading the Caliper after I put the new pads on, I believe because I had used a C-Clamp to collapse the Piston, I believe I was too Off-Center on the Caliper & accidentally Tweaked the Caliper Piston over to one side, just enough so it started to drag on the Rotor & didn't seem to have enough pressure on the Rotor when braking. The only other thing I can thing is that one Caliper just happened to get worse after I installed new Pads..
    ***With that said, your feedback on the matter of the Caliper issue I had would be cool..... Thanks again for the video. You got right to the point, plus you don't have all that ''Blah-Blah-Blah'' throughout your video like some mechanics do. Why some guys do that is confusing to me. When I search UA-cam for a repair video about replacing Calipers, Rotors & Pads, I'd rather watch one where the mechanic doesn't decide it would be a great idea to go completely off topic lol....... Thanks again, MD............

      @richardbadish6990 2 роки тому

      I doubt that you damaged or tweaked the piston. I should straighten out once pressure is applied and begins pushing against a flat surface. Which therefore should fix itself. As for brakes dragging. There's a couple things it could be. And be much more likely then your tweaked piston. 1. Dirty and rusty slide pins. Aka the bolts that the caliper mounts too. These do get nasty and rusty requiring them to be clean and possibly polished with a fine grit sand paper. Then it needs grease reapplied to the pins. If u feel like it's still dragging. It could be the pads themselves. At least on the caliper side. The Lil metal clip looking things that coke with pads and or new calipers. Are either really crusty not allowing them to slide side to side.. Also if you are trying to turn the rotor and hub by hand. And think it's actually dragging. It's not, its just tight because of you pumping the breaks. There's no return springs so once they are pressed against the rotor. They stay put, until you actually start rolling with weight on the wheel. There's a slight lateral runout on the rotor that forces the pads away from the rotor. So just keep all that in mind when changing brakes.

      Important note: leave the cap off the brake fluid reservoir when doing this. I kept leaving the cap on and wasnt getting any fluid coming out with the vacuum pump. Turns out that leaving the cap on the reservoir creates a vacuum in the line and when you use the pump, you're just fighting the vacuum and cancelling it out (so nothing gets pulled out).

      I put a new master cylinder and new booster, i checked my booster push rod clearance and i bench bleed the master,not perfect like i wanted to but i did do it,my master has 3 fittings instead of the normal 2,thats why it was a challenge to bench bleed it,it has your 2 normal side ports and one on the bottom (i know,very strange)when the car is off, rock hard pedal, as soon as i turn it on it goes to the floor,car does stop but its just not a good feeling pedal.
      Me and my buddy had bleed it 3 times,the backs are drums and there dont seem to be a lot of pressure coming out of them, the front ones are great, you bleed them and they will hit the inner fender with force but the back ones so so.

  • @michaelmclernon4929
    @michaelmclernon4929 6 років тому +45

    Vacuum bleeders seem like the perfect solution, but putting a vacuum on a wheel cylinder can pull air in past the seal cups in the cylinder, as well as the bleed nipple threads. This usually shows up as fine micro bubbles in the bleed hose between the cylinder and reservoir. The piston seals are meant to seal under pressure, and seal better as pressure goes up. Vacuum just pulls air right past the seal lips. Vacuum bleeders do serve a purpose though, if you need to do a rough bleed in a hurry, as long as you finish off with a pedal bleed.

    @black.eagle.1903 Рік тому

    There's something I'm curious about. When we pump this device, I think it only bleeds the main cylinder and the line between the wheel and cylinder. After a while, when the hydraulics in this line run out, won't the air flow again? I think it is necessary to constantly send hydraulic fluid from the master cylinder to completely remove the air. I don't think the tool is strong enough to pull hydraulics through the master cylinder. Can someone explain the truth?

    • @stinkycheese804
      @stinkycheese804 Рік тому

      No idea what falsehood you are imagining but it is not correct. You simply pump the tool to create vac, and it pulls fluid from the master cylinder reservoir, down through the master cylinder, then through the hard line, to the soft line at the wheel, and through the caliper piston chamber and out the bleeder screw at the top. That is a complete trip through the entire circuit for that wheel, EXCEPT any air that may or may not be trapped in your ABS module.
      There was really no "truth" to explain. You were simply wrong in your misunderstanding and it was always the same information that holds true.

    My brake fluid has turned green. I would pump til I don't see green any more. Just gotta keep an eye on the fluid level or be prepared to get it towed to a shop. My car is a Volkswagen so I first thought it may have been ATE Super Blue (it is very popular with us European and German car owners) mixed with regular yellow/clear fluid giving a green color. That might not be the case for me.

    • @stinkycheese804
      @stinkycheese804 Рік тому

      It is normal for it to turn green after contaminants cause the copper tubing seam to corrode. While it is normal, eventually that corrosion will require replacing the brake lines, but the first time you see it green isn't necessarily a sign it is due for that yet, but at the same time, better safe than sorry when it comes to brakes. IMO they more often fail from rust through from the outside in addition to the interior wall compromise so checking the outside is often a better gauge of when they are due for replacement to stay safe.

    I was doing this the other day and had soo many bubbles. I had a problem with my rear caliper- it would not pull fluid through. There was debris in the line (high mileage vehicle) so I had to remove the caliper, open the bleeder and compress the caliper, then pulled parking brake and compressed it again, put caliper back on and did a final bleed. Pain in the ass, but I just did my brakes and I knew there was something wrong with that caliper because I had a hell of a time compressing it to fit the pads.

I heard this from a GMC Tech veteran who said that I might need to hook up scanner just like the GMC trucks. I hope u can help with good info.

      ?? Plenty of people do it fine with a longer hose than 1.5". If it decreases the vac a bit, it will just take a bit longer and more pumps of the tool to finish. This beats having too short a line and not being able to position the reservoir cup well and ending up with brake fluid in the pump which you then need to clean out before it causes damage.

Further, teflon tape is resistant to brake fluid and practically any other chemical you're likely to buy as a civilian.
