Cleaning ABS sensor magnets

Trunk Monkey · 05-19-05, 09:54 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.

Is the ABS light staying on? Are the brakes pulsing when stopping? What year truck do you have? More information is needed.

I had the same problem about 3 months ago, ABS would only activate when stopping slowly. The shop I had do my front wheel bearings tried to say it was my off brand tire! (same size and tread depth different ply). I didn't buy it. I asked them to go back through it and it was either shims or dirty sensor. Either way didn't cost a thing. Good luck.

I too have been having the exact problems. When i slow down to a slow stop 60% of the time I get the pulsating brake. Then every other time I drive the abs sensor light comes on. Im getting my rear o2 sensor done this week and going to check the magnets as well. Word on the street is 515 for new abs sensors. OUCH that would hurt alot. But I will let you know the status at the end of the week. Thanks for eve1s help. God Bess America dont forget to vote.
