2002 tahoe breaks lock up during driving

The breaks drag and the wheels get pretty hot.
How do I know if the master cylinder is going out?
How do I know if the booster is going out.
I press on the breaks before starting, and then the break pedal goes down a bit after starting. Does that mean the booster is ok?
When driving the vehicle slows down and comes to a complete stop without applying the breaks
Help!! 4-wheel disc brakes on 4x4 worked well for 6 yrs - then grinding noise of 'metal on metal'. RR caliper had seized and inside pad wore down to metal. Intalled new pads on both rear wheels, used c-clamp to slowly compress pistons - no apparent problems during replacement... Now, when driving, the rear brakes drag and both the rear discs get smoking hot, so much so that the vehicle slows down and comes to a complete stop without applying the brakes. Front pads are fine - discs are cool to touch. The brake fluid resevoir level is half an inch higher now than before the pad change - attributed that to pistons not being extended at far with new pads. Did not open any bleed valves or add/remove any brake fluid. No visible fluid leaks anywhere. Don't have the common rusted brake-lines issue. Can't figure out how to get the pressure to release on the rear pistons.

    Take the truck to a professional and have the rear brake pads, rotors, calipers and brake fluid replaced. You should not be doing this work yourself. You are not qualified. I am not saying this to be mean, just safe and sensible. You have probably wasted more fuel because of this problem than the proper repair would have cost.

It sounds like the rear calipers are bad. Raise the rear wheels and see if you can turn the tires. If you can't, open the bleeder. If you still can't replace the caliper. If you can turn the wheel after you open the bleeder, replace the brake hose to that wheel.

2002 chevy tahoe no front brakes only rear brakes


IT appears that only half of the master cylinder has bled properly. Try loosing the pipe nuts at the m/cyl and gently pump the pedal until you get fluid out of both lines. Then re-bleed the system starting at the longest line first ending at the shortest. Some master cylinders have a plunger fitted in the middle of the cylinder and this is there to still have brakes if a line fails. It may be necessary to remove it an plug the hole temporarily while you bleed the system as to stops one piston in the cylinder from moving and allowing proper bleeding

It's a bad caliper on that wheel or a faulty master boot cylinder. Replace the caliper first, the rear calipers are usually fairly inexpensive.

Rear ABS Light/Rear brakes drag sometimes


The only moving parts on brake's are caliper's and master cylinder.The rest are just pipe's. Dosent sound like the master cylinder as the two back brakes should lock not one. It still sounds like caliper's. Can you be sure they have changed them If it were mine I would get someone independent to check they have done the work they say they done.

2002 tahoe breaks lock up during driving


i would check front and rear brakes if rears are drum brakes i would inspect springs and hardware making sure everthing is conected and in place also make sure they are adjusted properly in the front and if rear disc i would make sure to grease caliper slides these allow caliper to move and its important that all moving brake parts are free push caliper pistons in alittle to see if they are sized or not booster is ok and most of the time when master goes it will leak where it meets booster and you will have a low brake pedal or no brakes

2002 kia sportage 2wd brakes sticking


hi check all your brake linnings for contamination especially brake fluid on the linnings if this is ok you have a build up of pressure if its possible for you drive till the brakes start to lock up get out go to each wheel see if any of them is getting hot if so the problem is on that wheel jack it up to see if the wheel is locking if its red hot it will be sticking then try the rest of the wheels one at a time jack them up see if its one wheel or all if its one wheel release the bleed nut on that wheel see if it releases if it does it must be fitted with a pressure regulator to that wheel replace it . now if its all wheels its more likely to be the brake master cylinder or if fitted pressure regulator that supplies all the wheels a long shot i cannot see but better to mention it the brake pedal is not sticking and holding down yates210456
