Cadillac STS Posted October 26, 2004 Report Share Posted October 26, 2004 Hi everyone, I just installed new ceramic brake pads on the rear rotors. Well I didn’t bleed the system and now my brake pedal goes all the way to the floor and only feels like the front is catching. Was it because I didn’t bleed it? Also I accidentally removed the caliper piston on one side and popped it out, I put it back in and everything felt tight but im guessing I put an air bubble in the hoses? I need help guy I have school tomorrow morning! Link to comment Share on other sites More sharing options...
TDK Posted October 26, 2004 Report Share Posted October 26, 2004 As you already noted, this seems like the classic case of not bleeding the brakes. You probalby need some one to help you bleed the brakes properly. Did you check the master cylinder level? It could be low if a lot a fluid was lost. This is not a job to rush or to drive with crappy brakes. If you can't get a friend to help tonight, then maybe they will give you a ride to school tomorrow morning? Good luck Add power to leave problems behind. Most braking is just - poor planning. Link to comment Share on other sites More sharing options...

KHE Posted October 26, 2004 Report Share Posted October 26, 2004 Normally, you do not need to bleed the brakes when replacing pads but since you removed the piston from the caliper, there is air in that line and you must bleed the brakes.... Double check to make sure the boot/seal is not damaged and make sure it is in the proper positionwhen the piston is retracted.

I agree, anytime you remove the piston there is a possibility the boot will be damaged or not sealed. check to see if there is any leakage at that caliper and bleed the brakes.

an01sts Posted October 27, 2004 Report Share Posted October 27, 2004 If you haven't got it fixed yet or for future reference, lots of brakes can be gravity bleed. You take the master cylinder cover off, loosen or remove the bleeder, and let gravity siphon the air out. Some cars won't gravity bleed, but I have done lots of cars that were bone dry from the master cylinder to the bleeders. Never once did I touch the pedal. After I get some age on the car, and plan to replace the brake fluid, I'll try to gravity bleed. (The thing that you have to make sure of is that you don't let the resivor run dry; otherwise, you'll be starting from the beginning.) Link to comment Share on other sites More sharing options...
gc_caddy Posted October 27, 2004 Report Share Posted October 27, 2004 Have you set and released the parking brakes several times, to adjust the rear brakes? Link to comment Share on other sites More sharing options...
