My rolla is a 99 and whenever I stop, my brake pedal vibrates. If I step on the brakes real hard, sometimes the vibration would go away. I went to many shops to check out my car and everybody say the same thing that my brakes are good and my rotors are good too. If someone can guide me to what is the problem, I would definately appreciate it.

check your caliper bolts. if they're loose it may cause that vibrating

Pulsing brake pedal usually indicates warped rotors.


Did the shops check rotor thickness and true-ness?

Yeah, sounds like they are warped. They don;t have to be warped much to feel it. Take them off and to a machine shop and get them turned, it only takes about 5 minutes a side to get them off and on.

Keep in mind that the more you get your rotors turned, the thinner they become, and the thinner they become, the more susceptible they are to warping. Personally, I will get my rotors turned once. The next time they start to warp, I replace them.

You could try to re-bed your pads to the rotors. Sometimes brake pad material deposits unevenly to the rotors causing the symptoms of warped rotors. Do a google search on how to re-bed pads. Generally you'll do a handful of hard stops from 60-20mph with a minute between each stop to let everything cool down.

If that doesn't work look into replacing the rotors.

True, though the rotors have the manufacturers replacement recommendations on them and most places will follow that.

thanks everybody for your contribution. I deeply appreciate it. I will be changing my rotors and brakes very soon and i will keep yall up to date with it. Thanks again everybody!

drums dont get warpped. Called out-of round. and depends on if car has servo or non-servo rear drums. parallism on front rotos is factor also.

most likely have replace drums, rotor, pads, rear shoes, and flush brake system. 150+

I would place money that given it's under light to normal braking, the drums have little to no play in this scenario, not to mention if he is feeling the shaking that much, it's most likely coming through the steering. Not even sure how drums got brought in to this as every post is rotors rotors rotors.

Plus I just had the same issue like 3 weeks ago.
