Cleaning ABS sensor magnets

Trunk Monkey · 05-19-05, 10:54 PM

My 80 has been having ABS issues. Started with the ABS activating when I was braking to a slow stop. I pulled the sensors and cleaned them, didn't see anything on them other than grease. That took care of it for a couple days, but now the ABS light is on permanently.

I'm going to pull the code and see if the front sensors are bad. My pocketbook hopes not.

For anyone that's thought about cleaning the magnets, it's a .5 banana job, here's a couple pics.

You may be in for an expensive times. I had a similar problem when a "Cruiser shop" botched a knuckle job. There are some shims that helped for a brief while. Then the symptoms came back. I ended up having to send CDan about $300 to fix the ABS.

Unfortunately, that wasn't all they messed up with the knuckles.

is that an "after" shot of the abs sensor harness after cleaning? It looks brand new. Mine is caked in crap and I think it is black.

Nope, just as it was on the knuckle. The shot of the magnet is after I cleaned it. I'm guessing the ABS system is tempermental, the light is back off this morning.

I can feel the abs activating just before stopping. At first I thought it was the break sticking. The garage I bought it from told me it's because it's lifted about 6 inches at the rear. Also the abs light comes on occasionally and then this problem is gone.

I'm new to this vechicle and would appreciate any advice.

Just hack all of that ABS stuff off!!

Sell it and you've made some money and have a vehicle that brakes better (at least in my opinion).

I'm in the process of taking out all of the wiring for ABS and getting rid of the ABS box in the engine compartment as well. once that's out, i'll have a nice open area for some engine compartment accessories.
