2002 Explorer Brake Problem
When I drive my daughter's Explorer the brake pedal doesn't get firm until it is almost to the floor. They stop fine, except they seem so low. To me they seem mushy as first then become firm. Is his normal? How do you raise the height of the brake pedal's stopping point?

Not sure why you would need to ask if this is normal. Anyway, as pads wear the caliper pistons have to extend more to clamp the rotor; if the master cylinder's fluid level hasn't been checked, start there.

Definitely check the fluid level, then bleed the system, get all the air out of the system. If there is no improvement, check the master cylinder for internal leakage and/or air trapped in master.. (may need bench bleeding)...

"2002 is disk on all 4, so that would not apply as the pistons should self adjust as the pads wear (unless the calipers/slides are seized)"
If that's correct, then why does the fluid level rise when the pistons are c-clamped back into the calipers prior to pad replacement?

BTW, old fluid must never be forced back up to master cylinder, open bleed when retracting pistons and top up with fresh Brake fluid.....

yes, you wouldn't need to adjust the peddle. If you have an un-normally soft peddle then you have some type of problem. It is either vacume, fluid, or air. I agree that you should bleed the brake lines first.
