1995 850...ABS/TRACS problems...still

Experiencing ABS/TRACS problems?

chef » Hi guys, Since i got my car this past summer, I am always hearing a “ticking” noise when applying brakes, at lower speeds. When applying the brakes, i get the ticking, then the pedal vibrates/grinds(ABS), and comes to a stop. Lately it seems that the TRACS wanted to join the fun…and at times when taking off from a stop the TRACS grinding kicks in and i have to lightly apply brakes for it to stop working and the car works okay.

The thing is that i know that the pre-96 850’s had a more robust ABS module and i’m wondering why this is happening? I was thinking maybe dirty sensors and/or speed sensor rings? I also did a full brake bleed on the car. I tried to take off the screw holding in the right left ABS sensor on the caliper but snapped it. I don’t to have all broken screws on my case. Is there another way to clean out the ABS sensors? can the problem be something else? also, where is the ABS module located on a 95 850? thanks

If it’s the sensors

The places to clean the sensors on the early ABS systems is the reluctance rings on the axles (front) or the hubs (on the rear) They are magnets that tend to collect the metal that has worn off of the brake calipers. The sensors are just above the rings and they will get cleaned in the process.

The front rings are directly behind the hubs but you can get to them without really removing anything. The rears are located inside of the drums for the parking brake and you need to remove the calipers and the rotors to get to them.
