Okay, here's a list of all the parts required to swap to 1LE brakes. I don't even remember who I got the price quote from, so I don't know how valid it is now. But it is close.

Also you will need the inner and outer wheel bearings... GM had trouble getting the part #s for these and even sent me some wrong bearings. I ended up getting them at Pep Boys... and I found out it is easier to ask for parts for an '89 Turbo Trans Am than trying to explain 1LE.

DAMN the UBB and its space before tables!!! Scroll down to see the list...

Just to add a couple of brake related things here:

Master cylinders:

If you have '82-'88 rear disc brakes, your master cylinder is a different part number than all other combinations. '82-'88 rear disc use one part number, and '82-'92 rear drum and '89-'92 rear disc use the same part number.

Proportioning valves:

A lot of confusion with this, as near as I can tell there are three 1LE proportioning valves:

P/N 14089496 1989 1st design: M1.0 tube nut threads
P/N 10136840 1989 2nd design: M1.5 tube nut threads
P/N 10136840 1990-'92: M1.5 tube nut threads.

The first number would be used on '84-'88 F-bodies with drum rears, or with upgraded '89+ style rear brakes... '83 and earlier use non-metric threads, which would require serious brake line modification to work. At minimum you'd have to cut the nuts off the end of the tube and re-flare.

It's not clear what is used on a car with '82-'88 style rear brakes, since the master cylinder used with that system was NEVER combined with 1LE brakes. I'd suggest you upgrade to the newer rear brakes at the same time, and use the first 1LE valve.

If you have an '89 car you'll need to figure out what kind of nuts you have on your system... '90-'92 cars will use the last part no.

Hope this helps!

Also, there's a cheaper way of doing it if you are satisfied with modifying your stock spindles, go to Dan Burk's website( http://www.isthq.com/%7Edan/1LEbrake.html ). Be aware that a LOT of the smaller parts included on my list are NOT included on his .

If I'm missing stuff, why not email me and tell me so? I'd fix it! Remember, I've not yet upgraded the front brakes on my T/A due to feebleness of engine and wallet... but that's changing. At least, the engine part anyway.

Sorry, wasn't meant to be an insult or anything. Quite frankly, I didn't even think of e-mailing you .
