I recently replaced the front brake pads on the 124 (1990 300TE). We had to park it for a while due to insurance problems but now that it's been fixed my mom drives it daily. But she's been reporting that the brakes do not function properly. She says the pedal is pushing against her feet sometimes when she brakes, and that the car "slides" forward as if it's not braking.

What did I do wrong with the brake repair? I would think this is the ABS sensing some trouble, and maybe it's been posted before, but I don't know what key words to look for. The brakes worked well after replacing the pads, which was around March or early April I think. This problem only appeared recently. And it only appears intermittently. Most of the time it would brake normally, but sometimes it would just do that.

Before I forget I also rememebered that one of the two 13mm (or were they 15mm?) bolts holding the floating type calipers in (with blue Loctite) was a bit loose in that the bolt and its nut were spinning somewhat freely but the caliper was held in place nonetheless. These bolts are the ones you have to remove to access the calipers by the way. It was like this for both wheels so I didn't think much of it. Are these supposed to be really tight? I tightened them as much as I could but it was hard holding the nut in place while I tightened the bolt because the gap wasn't wide enough for what I think was a 15mm open end wrench.

Please advise. Thanks.
