The rear rotors and calipers on my 87 GTA appear to be in good shape, and so I'd like to replace just the pads as I think I've got about 30% left per side. A couple of questions, are the factory pads on the rear brakes the same as the front? I know the rears are a PITA to do compared to the front, but is there a sticky or some type of instructions on how to do them?
Do you have the Delco-Moraine Cast-Iron Brake Calipers?
I am not certain that I am recalling correctly, but I believe that the 1987 GTAs came with PBR Aluminum Rear Brake Calipers.
If you do not know what you have...
Post some images of the Brake Calipers.
PBRs came in 89. 88, if you count the four 1LE Camaros. 87 still had the DM rear calipers.
So assuming the rear brakes are still factory 1987 rears, and haven't been swapped to PBR, then yes, the rear pads are the same size and fit as the front pads. Front and rear actually had different pad designs, D154 in front, and D202 (I think is the designation) in the rear, but they're the same size and fit. And many pad manufacturers only offer D154 for both, front and rear. The only difference in fitment is a clip that attaches to the backing plate of the front pads that pops into the piston. You simply don't attach that clip to the rear pads.
I am just dealing with rear discs on my ‘88 GTA. What a PIA. The design sucks. The emergency brake cable needs removed to get the the caliper slide bolts. The brake line is not really long enough to service so I unfortunately unhooked the RH one. One thing of note. While the front and rear pads are the same dimensionally. I found the new pads I got were too thick. So buyer beware.
Getting rear drilled and slotted rotors have proved elusive with “supply chain issues.” I did find front ones from Brake Motive on eBay.
Me also, since 2 days I repair the caliper with new kit of gasket and now I hesitate to keep the old pads(not reallly used but since 1987)
I buyed this ref (ACDelco Gold 17D202M) and two caliper NUGEON9717246B (carefully)( yesterday on RA.
on my GTA 87, I believe what I had the original brakes pads, it is "stock" to stick them ? And I don't understand how to put the shoe dampening spring ....

I am trying to get all the performance I can out of this brake system design with rotors that are drilled and slotted. May be a pipe dream.
Fyi the drilled and slotted rotor isnt going to give you any performance advantage for a daily driver.In fact it will make your braking worse for a street car with average pads. Get a quality coated rotor and a quality pad will do you more justice than buying some rotor blank that had holes drilled and a groove machined into it that will more than surely crack between the drilled holes and shorten pad life and more brake dust than you can wash off your wheels per week. Leave the slotted rotors and performance pads for the track where they will belong and then switch back to the street pads/rotors for the street.
