dang. it must be seized in closed position. i bet that is what happened to mine. in my case it was left front that was still open but blocked making the front left grab ling after the front right. this pulled the car right on hard braking.Well got the ABS unit back together today. Cooling off the o-ring worked a treat (fridge was enough).
But, I still can't get compressed air to blow through the RF. Running out of ideas on how to clean this thing.
Starting to look like my only option will be to either find a solenoid or a used ABS Modulator Pump.
Awesome, sounds like a plan.read through it. i think i can handle the disassembly with tools on hand.
see if northern corvette can source you one cheap and if not ill send you a solenoid.
For just the solenoid? No one has a solenoid so far, or thinks there is a good chance they will find one. So no pricing...did they give you pricing?
Welcome to the forum, nice car!Hi there everyone!
A new 1987 C4 owner from Kitchener-Waterloo, joining you here. Just picked up our Nassau Blue (Medium Blue) C4 last week, we trailered it home since it's so cold here! -15C is not ideal weather to be loading a car, but you do what you have too.
The car is blue on blue with about 117,000 kms on the odometer. 4+3 Doug Nash manual, which I believe was required in '87 for the Z51 packaged. Overall, optioned pretty highly. The last owner only put about 3,000 kms on it in the last 3 years, so needs full servicing and tune up to bring it up to our standards. In good shape otherwise, though.
One thing I'm already learning from reading some of the last threads here, is the availability (or lack there of!) of 255/50R16 tires. The DOT dates on the current Dunlops is 2003, so they are just too old to try and eek any further life out of them. I've been searching everywhere for BFGooderich g-Force Sport Comp-2 tires, but there are just none available. Don't want to give up on them, but seems it's also true they may no longer be produced. Hope they change their mind! Anyone heard any further updates? My sources here say they have no production date set in the system.
I'm aware of some of the Toyo Proxes options (RA1 and R888R), however, my plan is to regularly drive the car from May - Oct. Not sure how well these tires would be on the street, especially in the Spring and Fall temps. The final option is looking at 245/50R16 tires. These are not that common either, but I do have a source for some Cooper Zeon RS3-G1 tires in stock and available. The car has the 9.5" wide tires, so I understand the 245 might be right at the minimum.
If anyone has an other tire ideas, or comments on running either the RA1s, or running 245s, I am all ears!
Look forward to learning as much as I can from all of you, and thanks in advance for your help.
Congrats , it looks good. I have found over the years, that nothing gets fixed quick, but when its fixed it still puts that grin on your face.Happy Thanksgiving!
Lots to be thankful this year, including a C4 that is back on the road!! Thanks to everyone for the help along the way.

The "new" ABS unit got here last week, and we spent a few hours yesterday and today getting it installed in the car. Funny enough we still ran into the issue of getting the front MC brake line to thread back into the ABS pump. Took us over 2 hours to finally get it to thread. I can't think of anything that has tested patience this much before haha. The other 4 lines took 10 minutes combined to get threaded in. Sigh. Anyways, the brake bleeding went super smooth and we knew pretty quickly that our issue had been resolved.
Took it for a nice long test drive, and I can thankfully report back that the brakes are buttery smooth now. WOW! What a difference. Really drives nice.
The goal now is to drive it as much as I can before winter! Woohoo!
Hope you all had an awesome Thanksgiving as well!
All good, no worries. Still looking for the thread. The tire set I found were practically brand new anyways, would be hard for me to rationalize buying another new set just to store.unfortunately i think all 300 sold.
