Brakes After Pad Replacement

Question:

Hello, I recently replaced the front brake pads on my 1999 Explorer.  No difficulties were experienced.  However, I find that when braking, there is a soft kind of crunching sound coming from around the pedal.  It will do this even when the car is stopped and the brake pedal is pushed.  The car stops fine and there is no change in brake fluid level.  Could this sound have something to do with the antilock system?  Is there additional work that needs to be done after simply replacing the pads? Thanks for any help you can provide.

I wonder if some gunk got stirred up in your master cylinder when you pushed the caliper pistons back in.  You might try bleeding the hell out of the brakes.

I had a similar problem on my ‘96 Exp. However, I knew right away that it was related to ABS malfunction. Car would break OK at speed, but coming to a stop a crunching (or grinding) sound would come up and pedal   would feel alive, pulsating back against the foot – this is normal for ABS, and is easy to recognize. Also, at about 10-15 kph a slight twine would be heard from left side of engine compartment – that would be ABS    control valve doing self-test. Since this occured after the brake pad replacement, I rechecked the pads, and they were fine. Then a garage mechanic run diagnostic and found faulty wheel speed sensor on right wheel. He phoned FORD dealer who insisted that both side sensors should be changed simultaneosly, but mechanic proposed to replace only the faulty one and see how it goes from there. No braking problems since Z
