I was trying to rebuild the rear calipers on my 9 bolt and im not sure how it goes back together after it poped apart was wondering if anyone has a guide on how to rebuild them?

Should i go ahead and get that kit not sure if the rear will need that recall kit seeing how the rear is from an 86 ta..? because the autopart store here have the overhaul kits minus the new piston and spring

I don't rebuild calipers unless they're bad.

I'd also put a lot more effort into swapping to 89-92 rear discs than repairing the early iron caliper discs. Hard to find caliper brackets be damned.

As to the identification of your as pre or post-recall, I'd post in the brake forum here on thirdgen instead of the transmissions and drivetrain forum.

I thought about the later calipers but not sure what I would.have to do for.the swap any info? Cuse I would like to use newer ones would look better on my 88 also there all over the local pull a part out here

Here's the general idea for 89-97 PBR's:

The 98+ is easy as well.

got a set of aluminum PBRs and rotors but is there any other way to mount them on my bw 9bolt by maybe modifying the stock mounting plates or the ones that the car i got the PBRs off of? because it seems there asking quite a bit on the sites in that link for the kit

No.

Members have modified the backing plates, yes, but I'd feel uneasy about it. A search no doubt would turn up some info.

Here are new 9-bolt backing plates (though you'd still need parking brake cables, combination valve and so on):

Great info! But im kinda confused on the pbrake cable do I use the brackets off the car I got the brakes off of and can I use the cable too? Also will the proportion valve off that car work too? Not sure of the year but its all off a v6 camaro

What year is the donor car?

JamesC

J0386

im not sure what the year is but dont think its later then a 96 but it says PBR on the brakes and says made in Australia but dont know if that will help and cant get back out to the donor car till tuesday

PBR's were used on 89-97 and 98+ (though the design is different for the latter). Since your 88 has a tunnel-mounted parking brake adjuster and the fourthgen car wouldn't, I doubt that the cables from the donor will work--might be worth a try, however. IIRC, the combination valve from the LT1, 93-97, won't fit, the LS1, 98+, will. You can purchase a modified 1LE valve from ED Miller.

Ok ill grab the cable from the donor car and guess ill just buy the combo valve but still confused on how the ebrake would hook up because the car I got the pbrs off of the ebrake was set up like a drum brake behind the rotor? Would I transfer all that over to the 9bolt?

JamesC

Humm, sounds like the LS1 set-up to me and that set-up is made for a 10-bolt.

JamesC

The car had a v6 in it though so does that mean its a 98+? And will it still work on my 9bolt? Man im confused all to Hell..

The following is a caliper (89-97) that will fit a 9- or 10-bolt with the correct backing plate:

Correct backing plate for the above (the rusty one is the 9-bolt. Note that the bolt pattern is different):

Here's the 98+:

The above is designed for a 10-bolt axle flange which is different than a 9-bolt. To my knowledge, no one makes a kit that will allow the swap. You might mod the 9-bolt axle flange, but I'd personally feel uneasy about it.

Wow thats way more then what I want to pay so my best bet would to just look for earlier brake calipers? And go from there? Damn now im stuck with some useless rotors and calipers .. Heres a pic of the setup guess i should have posted it first

J0386

Ok so i finally got the right calipers i hope... so heres a list of what i will need right?

Note that the cables are the second design and made for 90-92 cars with no tunnel adjustment. The first design is what I used on my 85, which has the tunnel adjustment. Part number in post #6.
