Several reasons. Your rotors could be warped. Its possible the proportioning valve isn't working correctly. Try a different type brake pad material. Make sure your wheel bearings are not too loose.
have you cleaned and lubed the caliper rails?
One of the most overlooked tasks when performing brake maintenance is the floating pins that the caliper mounts to. Make sure they are clean and well lubricated.
It's rare....because usually the master cylinder will allow pressure to bleed off. Not the other way around. But if you have replaced the calipers, this is the next thing I would check. I suppose it could be sticking.
have you tried the proportioning valve. sometimes dirt will get in there and clog the returns.
It is time to replace the brake calipers when they begin sticking closed or do not close all the way. You might also have a caliper that locks completely which needs to be replaced.
Check if the calipers are sticking.
I had one do this and I had to change the brake calipers. Problem was gone.
the pistons inside your calipers are sticking
The brake proportioning valve may be sticking, but this is very uncommon. Did you lubricate the slider pins on the caliber or replace them if they are rusted or corroded? Check all contact points and clean them off throughly. Apply brake lube to all contact points.
you need to change the spring in the clutch cylinder ,you find more info on at alfa .net
MORE THAN LIKELY THE RUBBER HOSE HAS SOMETHING IN IT. REPLACE THE HOSE SHOULD BE AS GOOD AS NEW.
Check for sticking calipers.
Defective Master cylinder?
master cylinder is sticking
you probably wont be able to move? or you can take it around the block, then when you get back dump some water on the calipers.. if it sizzles then there is a good chance they are sticking :)
It was the clutch master cylinder. It finally went completely out. I checked the slave cylinder, it looked and operated ok, so I assumed it was the master cylinder, I replaced it, it works now.
usually either the calipers have dirt in them and need to be replaced or the rubber lines leading to them have collapsed inside and need to be replaced.. really kills the gas mileage uh!! chevy has had problems with rear discs on these vehicles,70%of braking is on the front,30% on the rear. therefore the pistons get little use and stick. there are stainless sliders the calipers move on,you need to clean and lubricate them,this should stop the brakes from dragging. I have a 1999 Blazer and my rear brakes were grinding so I replaced the pads and rotors but had the same sticking problem. They dont offer a rebuild kit for my calipers so I had to replace the calipers also.
it need to be cleand its to much dirt inside the calipers bushing you dont need to chang it just open it and clean it and put it back its gune abe ok.
It may be the TCC Valve and electrical connections/hydraulics. It may have a bad connection, or valve may be sticking. It may be the TCC Valve and electrical connections/hydraulics. It may have a bad connection, or valve may be sticking.
well its sticking because of a bad caliper so replace the pass side caliper u should be fine ok thanks let me know
They Seldom Go Bad. Inspect For Leakage And Sticking. If Yours Stuck Replace It, And The Brake Hose Also. One Reason We Have Trouble With Calipers Is Not The Caliper But The Brake Hose. The Hose Will Rot On The Inside Not Allowing The Brake Fluid To Flow Back Into The Master Cylinder There For Causing Calipers To Stick. If Yours Isn`t Leaking It Should Be OK. Be Sure To Inspect The Brake Hoses, If They Appear Bad Replace Them. GOOD LUCK
Typically, sticking calipers are just worn calipers. You may just need to replace them. Calipers often stick when they get older and when they do so the brakes tend to wear rapidly and you'll get some pulling to one side. Always replace calipers on both sides so that both will function equally.
old break hose collapsing and or pistions sticking in calipers.
Sticking brake calipers. This can be caused by moisture in the brake fluid which will cause the calipers to rust. Replace the calibers and replace all the brake fluid. It can also be caused by driving with your foot on the brake.
If pads are bad you have to replace it, but it sounds like you have problems with calipers. Either you have to clean calipers or replace it. Check break fluid level. Check the breaking system, you might have some air in there.
Hi. If the brakes are sticking on it won't be the servo thats at fault it's sound more like the calipers need cleaning.
