great site guys, i just found it and i have a ton of Qs.i just bought my daughter her first car, a 86 T/A in great shape for a mi car, its not seen a winte from what i can tell.there is a three ring binder full of all the paper work from day one.. very cool..any way to my first Q.the rear brake line on the driver side of the housing, it seems to been replaced or rerouted due to a caliper replacement. i cannot for the life of me figure out were its original route and mounting points should be! the rubber hose from the caliper does not have a mounting point it is just hanging there with the hard line bent up to keep it from moving parts..does anyone have a rear picture they can email me of the proper routing and mounting points of the rear housing drivers side hard line and hose mount? thanks

The line to the driver's side caliper should be a hard line, the pass side flex. Note too that the calipers clock differently. You should be able to purchase a hard lines from one of the following sites:

I picked up an axle out of an 83 Trans Am from the junkyard for the posi and disc brakes, and it didn't have flex lines. The lines I replaced them with from InLine Tubes didn't have any provisions for them either. I had hard lines all the way to the calipers until I removed the brakes in favor of the LS1 style.

Maybe some of the later years between 83 and 89 had a flex line on one side

Interesting. I've never seen a car with hard lines to both sides--but I haven't seen them all. As a side note, an 89 with rear discs would have had flex lines to both sides.

so your saying that the drivers side hard line would go directly to the caliper, with out a flex? that would explain why the line is so long, but this caliper is made for a flex? maybe they put a pass caliper on it? would that work? i would still like to see a pic if anyone has one? thanks guys

Yes, of the lines I've seen, the driver's side his a hard line and connects directly to the caliper. The calipers are the same from side to side, which is why they're clocked differently.

I found a couple of mine from my axle swap. Best I have that show line routing.

This is the passenger side, note the caliper is clocked to the front of the axle. The hard line connects directly to the caliper.



And the driver side. The caliper is clocked to the rear of the axle. This one didn't have a flex line and connected identical to the passenger side (the same part number is used for both calipers). Mine made the same loop to connect to the caliper as the passenger side does.

Here are all the pics I have:



Modified for PBR calipers, the pass side is stock, the drivers side was shortened for the flex line there (stock caliper has hard line all the way there)

I am confused about the fittings on the brake lines. I'm swapping in a 9 bolt with discs from an 88 IROC and the only thing that I can find that threads into both calipers is a banjo bolt.

From the research that I have done, the passenger side has a rubber hose but the drivers side does not. The calipers are identical. I can't seem to find any brake line fittings that have the same thread as the banjo bolt, is there an adapter? From the pictures it looks like the line threads right into the caliper.

Thanks in advance for any help you can lend.

Answered my own question. I was looking through the parts that I had from the axle purchase and there is an adapter that the brake line screws into. A banjo bolt passes through that adapter and into the caliper.
