Hey all, I'm doing a complete suspension rebuild and grand am brake up grade this weekend. I just took a close look at the brake pads the thickness of the pads are different.
I've never seen anything like this before. Is this a normal 87 Grand Am thing? (Used same year as my Fiero to make it easy on my old mind).

Right off the top of my head I would say they have a longer travel of the calipers than the Fiero has, so they need thicker pads. Larry

I'm not saying there is a difference between the grand am pads and the Fiero pads. I'm saying a new pair of grand am pads for a given caliper, one pad has twice the thickness of it's matching pad.

From what I remember, I think you need the grand am rotors too. Did you use a C-Clamp to compress the brake caliper piston? You allso need to remove the cover on he brake fluid resivoure,so the piston will compress easyer.

Or...are the pads literally different thicknesses. Were they ever opened before? Perhaps you received a warranty set by accident?

On every set of Grand Am brake pads I've bought, the inboard pad was always thicker than the outboard pad. I'm not sure why. But it never caused me any problems.

Typical GM brake system... they are expecting the calipers to seize and the inboard pad to do all the work... LOL

This is a joke... kind of...

There is a kit for the brake piston work that you can rent from the loan a tool at various auto supply places. It allows you to turn in the piston. On the Grand Am caliper it is not critical, but if you use the Seville caliper on the back it is critical because you have to set your ebrake lever correctly. (about 1 turn from bottom dead center)

Hope this helps

Thanks everyone. I was only able to complete the engine cradle bushings, all the control arm bushings and new shocks and struts. Man were they shot. Had to cut out the lower control arm bolts out with a cutting wheel. Had to cut the frame to get to the cradle nut plates. Good news though, the rear frame rails are in better shape than a mid 80's car from the rust belt should be in, so I was happy to see that. I can't believe how much better the car rides and handles. I scared myself with how fast this thing will change lanes now. I'm in love all over again. I will probably do the brake swap the first weekend in May. I an currently just doing the four corner GA swap. But seriously considered the Seville calipers. The cost and potential (future) availability made me stick with the GA calipers on all four corners.
