The car is an 1987 it uses the bosche 202 pump used on several other types of cars. This was the first ABS units aviailable in any US car. So there is no traction control. The unit has lines for the two front brakes and on the unit applies the ABS to two back wheels at once. Nothing was hacked...

My ABS PUMP did not release the pressure on the line, we are not talking about increase pressure we are talking about releasing pressure. That is one of the steps you listed above releasing pressure. Why do my brakes work know that we have the new ABS pump in the car.

What about a stuck valve my pump is bosche 202 pump two lines for the front one for both wheels in the back. And my pump did have a stuck valve. The guy I calledl Gordon Kilabrew used to work at the factory, look him up. He said its rare but does happen. I changed out the pump and the car is...

My car is 87, I paid 100 + shipping the guy included the computer along with it. What year is your car it may be easier to get. Check to see if someone sell rebuilt pumps, my pump is not re-buildable.

I called Gordon Kilabrew sorry if I mis-spelled his name. He told me to disconnect the abs if the brake was still stuck then it was the abs pump. He said it is pretty rare, but it happens. Forget about getting a new one the have been out of stock for a long time its a bosce 202 pump. I bought...

Finally got to root cause of the problem. Stuck valve in ABS pump. Replaced pump, and bleed the brake system with a pressure bleeder. Everything works fine now. Thanks for all your help.

BTW the left side front does not act like this you can bleed the brakes without the car being on.

Ok Saturday, we pulled the line off again the rubber hose pump the brakes some fuild comes out, turn the car on and do that a lot fuild comes out. We installed the new caliper, same thing the car has to be on for fulid to get to the caliper, but the pressure stays on and lock the wheel. Any body...

Ok its Friday I was off from work today, this what I did, I pulled the fuse,and antilock brake lite stays on . It should no fuse, I had my wife pump the brakes and hold down the brake pedal old fashion way of bleeding brakes, a lot of fuild came out this time. But the wheel is still locked...

We did not try that, should I just pull the fuse?

No quick spurt just un-pressured dribble. What I meant to say is that the car pulls to the left as if the right brakes are not working. But the right side is diffentley dragging. Thank You.

We already changed the hose; stilled locked. But thanks anyway

Yes we did.

ABS comes on and goes out as soon as the car starts, brake hose was changed. Ok we will put the car on the lift and check the brake lines. BTW we can't bleed that brake nothing comes out of the caliper, but if you take the hose off the brake fulid will come out of the hose. Lastly I hear the...

Yes; and I also change out the left caliper and hose.

We have 1987 corvette 52,000 miles, and last year we changed the right front caliper because the boot was tourn and the caliper was locked closed. Since then the car pulls to the left, and we still have a locked caliper on the right front, I have changed to hose bleed and tried to bleed the...

Looks like I found a bad code for my 87 with climate control. The light was blinking I found the procedure on this site. The out side air temp sensor was bad. I replaced the unit, disconnected the battery to reset the codes. Its know showing 00 no codes but outside temp shows any were from 129f...

Does anyone have the procedure to extract the diag. codes for the climate control. The external temp is flashing when I start the car. It show -39 and -38 in the external temp when driven. I know the car needs a charge so I will have that done today. I just replace the ATC power control module...
