Either a bad caliper or wheel cylinder. In the majority of the cases, the cylinder is to blame. But if you want to be safe, replace both to cover your bases.

DEPENDS WHAT PROCEDURE YOU USE TO REPLACE THEM.IF YOU PUSHED THE CALIPER PISTONS IN WITHOUT OPENING THE BLEEDER AND USING A **** CLOSED THE BRAKE HOSES YOU MANAGED TO SENT BACKWARDS THE FLUID INTO THE MASTER CYLINDER WHERE IS THE POSSIBILITY TO CAUSE THE SEALS ROLLING IN AND ARE NOT HOLDING PRESSURE. THE OTHER REASON IS EITHER YOU NEED TIME UNTIL THE BRAKES BED ON THE DISCS SURFACES.

94' Honda Accord 5 door, Driver side caliper piston remains stuck in closed position constantly applying constant brake pressure to driver side front wheel brake piston.


if the caliper is ok it sounds like the flexiable hose is restrcted by the metal crimps on the hose corroded and crushing the reinforced rubber hose restricting the fluid returning back in to the system. change the hose

I have envoy brakes are realy noise


When you step on the brakes, the pads vibrate. It may be you didn't put the little gaskets, or anti-squall stuff on the BACK of the pads.
If your "kit" didn't include it, get some copper lube and apply to the back of the pads.
I know, means you have to pull the pads but it's either that or live with the noise.
Have fun:

2001 Silverado 2500 HD Why Rear brakes don't work after I installed new hydro-boost power booster, master cylinder, calipers, and pads. I bled master cylinder before installing, and brakes beginn


Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

'97 sunfire pulls hard to the right when brakes applied. Changed pads and rotors on front end and bleed brakes but made no difference. Any suggestions?


When you changed the pads did you notice if one side was worn more than the other? The most common cause of pulling when you apply the brakes is a seized caliper. It won't work and the other does all the braking. Your left caliper is likely seized and needs to be replaced. Hope this helps.

Right side rear brake drags


Remove all rust from pad and caliper sliding surfaces,eg metal to metal,not the pins,they get synthetic brake lube. Apply anti-seize to all sliding surfaces. Make sure you can screw in the rear caliper piston,if applicable, and manually ratchet up the parking brake,after caliper and pads are on. Bleed/Flush all 4 Wheels. Make sure you can slide the pads back and forth,before lubing end tabs. You may need to file a little off the ends or just remove the paint. Make sure parking brake cables are really releasing.

I changed the front pads on my 97 Sebring convertible. Also put on new rotors, and changed the calipers. My car bounces slightly, and if I apply the brakes hard, they become spongy. I have bled them off as...


Spongy means air present in the hydraulic system,I recommend check and recheck all of the brake system areas where air could enter(master cylinder,fittings,calipers,etc.)and bleed the entire system again.
Good luck !

Front brakes pull hard to right when applied


MAKE SURE THAT THE CALIPER WAS PROPERLY BLED AFTER INSTALLATION. YOU NEED TWO PEOPLE TO DO THIS. ONE TO PUMP THE BRAKES AND ONE TO OPEN THE BLEEDER VALVE.
