View Full Version : Brakes: Pads? Rotors? Calipers?

GAGT OWNERS:

I recently put new brake pads on my '99 GAGT. Rotors and calipers seemed fine, so I didn't replace 'em.

After about 6000 miles I am noticing that my brakes feel like they are "skipping". Sort of like they grip and then slip, grip and slip, and so on (this of course happens very fast and just makes for a hesitating, unsmoothe stop).

Could this be from warped rotors? Bad calipers? Pads? Any ideas?

I'd say Warped Rotors... if it is.. since they are warped... as the pad rides over the "uneven" curved part of the (warped side)rotor... you notice the slip ? .. so.. I think it's that.:rolleyes:

Thanks for the input. Makes sense what you say, since the pressure of the pads against the warped rotor would be too little as it contacts the warped part and then grip once it hits the true section of the rotor.

I'm hoping it's the rotors and I'll just replace them---easier than calipers (having to bleed the brakes and all).:thumbs:

Mine seems to do this only when I brake really hard... Also I believe that I have braked hard enough to get the ABS to activate but my ABS light doesn't come on.. and it does the thing that feels almost like its slipping.. is that the ABS and does it still work if the light isn't coming on? :confused:

Ya, warped rotors...every GA owner has this problem.

from my knowledge.. the ABS light doesn't come on when they are activated (in use).. it's suppose to only come on in the dash when they are malfunctioning (not working).....:boogie:

On the earlier versions of the GA's (like my '99 but the later versions stopped doing it): the LOW TRAC light comes on when the ABS brakes are engaging/have engaged or when the traction control is trying/have tried to control wheel-spin.


I heard with the GM OEM rotors (at least the fronts) should be changed out for new rotors every time the brake pads are changed because the rotors are not very high quality & warp easily as they get more used/thinned out.

Bite the bullet and get new rotors and pads all around. Thats what i did. Get good quality though.

what type of rotors do you guys recommend? I would like to get slotted rotors but from where? PFYC? are they good?

and do I need special pads for these rotors?

thanks

I got BENDIX rotors/fronts: $47.86 each
BENDIX rotors/rears: $38.49 each
The pads i dont remember exactly but fronts where like $38 and rears where like $28.

where did you get them and are they slotted?

you can get them anywhere. They are not slotted. I wanted slotted but it got to the point where i couldnt waite for them to get delivered so my shop hooked me up.

I think wagner rotors are cheaper, i think they are called wagner.

If you use a big C clamp to slowly push the piston back into the caliper, you won't have to bleed any fluid. The fluid gets pushed back up to the master cylinder.

WWW.Rockauto.com has Raybestos and Wagner, two or three

different ranges.
