Need Advice on Possible ASR/ABS Problem
Hi.
Found a '93. Car is absolutely gorgeous but there are a few possible problems so I thought I'd see if anyone could give me some input or advice.
Car drives perfect, EXCEPT there is some weirdness with brakes in a couple of ways.
1) Pedal pulses even when applied lightly. I was under the impression that you should not feel this unless the ABS was being activated due to a "panic" type stop.
2) There's some "grinding / chatter" type sound from the rear that occurs after you come to a stop and then take off again.
3) Both the ARS and ABS lights are lit up constantly. Based on what I've read, this seems to be a combined unit that controls both functions.
Also, only some of the functions work on the drivers power seat controls. No back and forth, no tilt. I’m guessing the motors are O.K., so does this sound like a switch problem?
I really like the car, and if not for these glitches it would probably be mine tonight, but I'd wanted to see if I'm looking at a major problem or something that can be corrected without some obscene amount of money.
Any advice would be greatly appreciated.

Re: Need Advice on Possible ASR/ABS Problem (BankBoy)
For the ABS and ASR lights, make sure the brake fluid is all the way full up to the proper mark. Low fluid, even a little low, can cause the lights to come on. I'm not sure if the pulsing has something to do with this... I thought that when those lights are on the ABS is disabled, so it shouldn't be pulsing from the ABS. Maybe warped rotor(s)? You should be able to tell from how it feels if it's a rotor problem or if it's pulsing from the ABS. If it's an ABS pulse, you may have a faulty wheel speed sensor.
