Pulse in back petal

check your sliders may need cleaned .but a pulse is normally bent rotors.

Is your ABS working properly? Under heavy braking the ABS should engage and 'pulse' the brakes on/off. It is normal to feel the brake petal flutter or pulse under your foot.

Under light braking there should be no pulsing as the ABS does not engage and you have changed the rotors and pads.

That's probably why the caliper may be hanging Si the pad or what's left of it will remain in contact rather than retracting.

Sounds like brake pads and rotors need to be replaced. Sounds like rotors are warped - explains pulsating. Metal on metal is worn pads.

Probably a disc brake pad scraping on a warped rotor as it goes around. When you apply the brakes the warped rotor causes the car to pulse or shake as the rotor goes around and applies the brake unevenly. You need a front brake job.

yes that is a very common feeling in warped rotors, if you feel the brake pedal the pulsing then you defintly have warped rotors, replace rotors and brake pads, never reuse pads when they have been in contact with a warped rotor, they will cause the new rotors to warp also

You need to have your brake pads replaced. They make that sound when they get worn down so you know to change them. There is a little piece of metal that rubs on the brake rotor to tell you this. Hope this helps

make sure you have full fluid then bleed the brakes again air can be a ***** to work out so just keep on doing it a few more time to all 4 brakes. look for any leaks while you are bleeding the brakes just to make sure. if your pedal is still soft it could be two things. rotors - did you have the rotors cut. if the rotors are worn down past thickness then your pedal will go farther that it is supposed too. you can bring them in to a napa and they will measure them for you and tell you what thickness they need to be. the last thing it could be would be a bad master cylinder you could try to replace that but i would try all other steps first.

You need to replace the master cylinder. If all else is good and the petal goes to the floor, that's really about all it could be.

Try checking the snorkel tube between the air cleaner and the intake. Open the hood, and have a friend try to rev the engine, and watch the tube...my '92's was collapsing and starving the engine, couldn't get more than 3500-4000 rpm. Could also be a fuel pump problem like low pressure or bad line.
