Saturday, after the Tidewater Sports Car Club meeting that no one here but me attended, I was driving back off base and hit a surprisingly large puddle at 15ish mph. When I hit the breaks my wheels locked up. My ABS was working perfectly fine before the puddle and not at all after. I have no warning lights on the dashboard and after 3 days my brakes still work like regular brakes. Has anyone had this issue before? And if so how did you fix it?
If it helps my 1987 turbo is relatively stock, and the brake pedal is travelling about an inch between no brakes, and full lock up.

Oh! The LeMon Turd. I was just saying that I didn't see any other 951's there. Hopefully you will make it past the gate for April's meet. I plan on participating as soon as I replace my worn out control arm bushings and fix my brakes.

I was the last driver in the LeMons car. My 951 is busy holding down a set of jackstands.
Have you started diagnosing your ABS? Any progress? If it were me, I'd probably remove the ABS system. The only thing ABS is good for, IMO, is to prevent flat spots on your tires if you're a bad driver. And in case you're curious, I have flat spots on my tires![Big Grin](https://rennlist.com/forums/images/smilies/biggrin.gif)
Your car looks really familiar. Does your dad live in Virginia Beach and is your dog an escape artist?

Generally if a sensor is broken of not working properly, the ABS light will show on the cluster. I had a broken rear sensor and my light was on.
You should still check everything, but its weird the light isn't on...

I am not sure this is an ABS failure. I've driven 944s with abs and without and I could only tell the system was activating under very hard braking. I wonder if something went wrong with your proportioning valve? I have had the rear brake part of my master cylinder fail where there was no fluid pressure to the back wheels.

My rear brakes definately still work because my nonexistant brake pads still squeak against my ruined rotors. I haven't had the chance yet to get it up on a lift, but I will tomorrow and I'll tell you what I see. My buddy thinks I might have a rock under one of my brake and that's causing the short brake pedal travel.

Figured it out. I wasn't going fast enough when I hit the brakes. I had to slam on the brakes today at about 60ish mph to avoid hitting an old lady and it worked.

Truth be told, I've only locked up a front wheel on my turbo w/o ABS, and I was trying to slow from north of 100 to 50 in a hurry. I've never given it that much pedal before.
My S2, I cant remember hearing and feeling the ABS before I wrecked it. However, it was sliding sideways so ABS wouldn't have worked anyways.
Josh- Whats this you say about your rear brakes not working? My rotors are really rough and look as though the pads aren't even touching the rotors. They should be flat and smooth in at least some parts. I had always felt like the car lacked brakes. It surely doesn't compare to my S2 in braking. Its possible for the rears to not work? Care to explain more?
