I’m a novice. While putting in new rotors I forgot to put in the bearings on the back side. This caused some kind of damage to my ABS modules because every time I brake the brakes grind like I’ve locked up on ice and the ABS light comes on. A friend who works on cars told me to go to a junk yard and replace modules on both sides but it still grinds. Any suggestions?

I removed the front brakes, calipers, and rotors. When I put the rotors back on I neglected to put the bearings on the back of the rotors. After assembling the rest of the parts I drove the vehicle for about a mile and got a grinding sound. A couple days later I had the truck towed to my work where the maintenance guy (Mike) found the problem with the back bearings and some ring and he put them on. I drove the vehicle home the next day but noticed the ABS would kick in every time I braked and the ABS light would come on. I contacted Mike and he said the ABS modules were worn down and needed replacing. I went to a junkyard and got replacement modules (I couldn’t find new parts at any parts store nor online). I replaced the driver’s side first thinking the sound was coming from that side and I only needed to replace same. However a few days later I replaced the passenger’s side when the ABS continued to engage while braking. Even after replacing both modules the ABS still pumps the brakes when I brake although the ABS light no longer comes on. About the only othe weird thing is when I drove the vehicle with worn modules my clock on the radio would reset to midnight every time I braked.

In in addition I checked both fuses, the ABS diode and the fluid level is fine too.

So you’re saying I might have to replace the rotors, bearings, and seal again?
