'90 ZR-1 brake refurbish options

Thinking I might have to do something like that, nice to know it's worked for someone before I have to resort to it.

Got 2 of 4 loose. Liquid wrenching the heck out of the others, we'll see if that helps.

Had to use a small ford wrench, but all old hoses are out. Nothing got too mangled.

Finally warm enough to make some progress on the brakes. New lines connected (not tight yet), they are definitely all longer than the originals, will have to make sure they stay clear of the wheels. Still have to clean up the front suspension, but need to move the ABS sensors out of the way first so I can get in there and scrub.

Cleaned up my mess under the car and arranged my old parts. Plan to hang on to them, but plan to get all new bolt hardware/pins/etc, looks like all available through Corvette Central. Will order this week.

In the meantime, as long as the weather holds out, will attempt to op-test the ABS sensors while I have them out of the hubs for cleaning & inspection of the sensor heads. The wiring sheath crumbled on me on three of them, guessing they are originals, the driver's front is in much better shape and looks newer. ABS fails self-test on this car since I've owned it, so would be nice to figure that out.

Finally got off my behind and tested all of my ABS sensors. The magnets all seems to be strong by just putting a small metal object up to them.

I then used the front drivers hub to check for output. The fronts sensors both gave very strong response on my multimeter, which was set to AC mV scale. Drivers front gave me roughly 300 - 400 mV, and the passenger front gave me well over that, 500 mV with an easy turn of the hub, and off scale high with a good hard spin. The rears gave much weaker response, both were around 50 - 60 mV.

Unfortunately when disconnecting the front passenger sensor the plug on the sensor end crumbled, so it will not be able to be reused.

The wheels, still drying in the paint shop.

Wheels look great! Did a shop do them for you? I'm in NJ looking for someone to refinish mine!

Local shop near me in West Chester, PA. Total was about $900 for the repaint, incuding strip/clean/prime/paint/clearcoat, and put new tires on (price doesn't include tires themselves, which I got separately from TireRack). Still have to get center caps, want to put black ones on.


Contact info for the shop is attached. Hansel treated me well. He gets a ton of work, and does brake calipers as well. My wheels did take a while as we went through several iterations of reburb ideas, and we agreed up front on no rush for these.

Going to pick them up here in a bit, so will post more pics in better light later.

Thanks btw.

Whereabouts in Jersey?

[tiegsd]

Wheels are home now. Very pleased with how they look. I went with the brightest silver I could find in the pallete, they have a bit of small flake in them.

New Michelins for shoes.

Time to start putting the old girl back together.
