I have a 86 TA 9bolt what's the PN for the rotors and pads are there any after market brakes for it like EBC and will a ls1 master bolt to 87 camaro booster would it do anygood what's better than the 1le C.V. its the only 1 that's looks oe and bolts right up

 

The 9- and 10-bolt share the same rotors, pads, calipers.

To answer the rest of your questions. The OE master will function fine. For the 86 J65 set-up, you need the standard disc combination valve for, say, an 84 to 88 car.

When I pull it up I. Get pads that are to small my rear pads are like my front if not bigger

 

have the parts guys look up something in the 91-92 years if needbe, may have to tell them "performance" brakes too

 

I'm not sure what brakes you're discussing. All 82-88 rear disc cars have 10.5" rotors and iron Delco-Moraine calipers--whether they're on a 9- or 10-bolt. The front and rear calipers look the same.

89-92 rear disc cars have 11.7" rotors and alum PBR calipers--whether they're on a 9- or 10-bolt. In these years the rear brakes are larger than the fronts unless the fronts are 1LE. Rotors/calipers may be called the 1LE or the performance package for this application.

The rear end I was told it was from a 86 trans am my car is a 87 got it with the car I took the pads off ad took it to them and no luck the caliper looks diff than the front the pads are bigger that the 10 bolt pads they pulled well I work at that parts store now and I will take it off 1 day and run threw the system sure the was just over looked glad they are the "same" so I can run better pads and rotors I was gonna do a 4th gen built 10 swap but ppl say the 9bolt 7.75 ring is better than the 7.62 even if built thanks guys

 

Are your real calipers aluminum.with fins or are they iron and look like the fronts?. If they are aluminum, they are the later brakes, so the axle is new than you were told.

The 9 bolt is a bit stronger, but parts are more expensive and hard to .find

 

Sojer, i know what you mean. i used to have an '87 IROC and the rear pads where the same as the front. same part number and everything. since the parts stores had issues with it, i just got to the point i went in and got 2 sets of front pads. the rear was a 9 bolt as well.

 

Can I use dot 5 any1 know its says don't use with abs are cars didn't come with that so. I do have a cert in brakes but all they tell u is what its base is. It seems better higher boiling point 475 I think and its not hydroscopic
