pulsating brake pedal

[RMORT]

My 03 cavalier has had the disc's trued-up twice now in only 16000 miles due to disc warping. Same problem with a 97 I used to have. And I am not hard on the brakes.. Anyone else have this problem??

Funny you mention disc warping. Just had both rotors replaced because they were terribly warped. Also had to replace the pads because of uneven wear.

Had the same problem. Went out and picked up a set of hawk performance pads and brembo drilled and slotted rotors. So far everything is great and I break like a wacko.

Some years ago there were some major claims against tire "specialists" who's job was to replace and install tires on vehicles. The major complaint was premature wear and warping of rotors. It was discovered that in their efforts to make the process speedy, most "specialists" chose to use impact guns and the like to install the bolts onto the studs. You can imagine how tight these nuts were cranked on. Heaven forbid you had to remove a wheel. Most folks had taken to including a johnson bar; or a piece of steel pipe to attach to the nut removal tool included with the vehicle.
Reinstalling the nuts onto the studs was supposed to be finalised with a torque wrench or something capable of doing so to X number of foot pounds.
Needless to say, a lot of "specialists" got dinged pretty badly for an assortment of repairs including stud replacement, new rotors, brake shoes, and even damages related to loss of work pay and worse. All because a cheap tire jockey was portrayed as a "specialist". Next time, observe the installer as your tires are serviced. If you see him take anything other than a tool capable of properly torqueing on the wheel nuts, complain and go elsewhere.
