HAve all new rotors and brake pads and shoes, but when you depress the brake pedal at times, it fills like something is wapping around the brake brake pedal to lock it, what could this be? No codes comes up on machine, keeps the car up and changes the oil every 3000 miles.

SOURCE: Brakes pulsate real hard

That is just the ABS system at work. It is supposed to prevent your wheels from locking which often makes the brake pulsate, especially in wet weather or or snow or ice. The only way to really stop this is to disable to ABS by unplugging it and removing the fuse. This will make the ABS light appear in your dash, but your brakes will stop pulsating.

Well this is very serious I hope you deal with it right away. You mentioned that sometimes the pedal was hard,do you mean that its all the way up and it doesnt feel like you have power brakes?? If so have you noticed any sounds like air escaping (swoosh sound when brakes applied)? Failure of the power booster causes pedal to become very hard and could possibly be your problem for hard pedal if I understood you correctly. check to make sure that vacuum to the booster is conected properly and hose not kinked..Now for the solution for the pedal fading to the floor... You either have air in your brake system, A bypassing master cylinder , or a hydraulic leak...Were your brakes serviced recently?? if so try bleeding your brake system first...That would be the first step if still the problem persist I would isolate exactly where the problem was coming from.. To do this you would start at the passenger rear wheel and line clamp the brake hose to make that part of your brake sytem inoperable...when clamped try your brakes and note if brakes improved or had know affect on system (when testing obviously im not suggesting you drive to determine results of test procedure)repeat test for each wheel you have isolated the problem when brakes feel normal with one wheel clamped,which ever it may be.. This isnt as hard as it might soun and if you are confused at all dont hesitate to ask questions... Remember the only dumb question is the one you fail to ask I would hate for you to get into an accident ... Good luck!!!

SOURCE: unable to remove front brake rotor

Hello, one "trick" is to grab a big hammer and hit the face of the rotor (the part that goes on the hub between the lug studs, NOT the brake pads ride on) several times. A lot of the vehicles I have done this with you really have to whack between the lugs pretty hard and a lot of times. Just make sure you don't hit the lug studs.

SOURCE: Pulsing sound and feel from wheels

Ok, if the wheel bearing assembly was installed incorrectly the wheel would wobble and you would have a disconcerting feeling in the steering wheel. The rotors have to be within factory specs to be turned safely. What I would do is have the rotors checked with a micrometer and replaced.

SOURCE: 1999 Pontiac Bonneville SE 3800 ABS Brake pedal will eventually reach floor after stopping while hold car stopped. Brake pads replaced less than 5000 miles ago. Fluid level at max and does not drop. O

I would replace the MASTER CYLINDER. BLEED AIR from master cylinder BEFORE INSTALLATION. Hope this helps
