One (maybe both) front brakes on my 93 are locking up under moderate pedal application. I noticed the drivers' side locking up driving home in the rain the other day. I checked the bearing play, greased the slider bolts and bled the caliper but the problem persists. Any ideas? Are there wheel speed sensors on the 93's or is this pre-ABS?

 

Time to replace the calipers. When mine started doing that I thought I would save $$ and rebuild them. wasted time lasted about 1 month so I just replaced both. Mine came with new pads.
