Hi all, Just pulled my 99C2 out for the summer and well It is behaving oddly. As my foot gets near the brake pedal it seems as though the pedal is pulling away from my foot. Just about how magnets aligned resist one another. The brakes work, but I have noticed that they may even be staying engaged for a second every one in a while. The pads are 4k old, rotors are all good, fluid is tops. Also can someone tell me what color the brake fluid is supposed to be? TIA!

I would suspect the booster. If it gets filled with water (I'm not quite sure how the water gets in, but I understand it's reasonable common) it can make the pedal feel sluggish.

Okay I've had a little more time driving to better describe the happenings. The first half of the pedal travel is acting like there is air in the system, but oddly enough the pedal "hangs" at the half way point(point where breaking begins) and I notice that I can pull it back with my foot and all is good but if it stays at the halfway mark then the brakes are minorly engaged.

All thoughts are appreciated.

Also on the SBJ I am currently looking for a set of SS brake lines any recommendations?

77K, 99C2, EVOM'd and Champ'd to the hilt. N/A

Any ideas on how to check if there is water in the booster. My cowl did flood due to clogged drains?

Oh and just so all know she has a doctors appt. next Thurs. to be flushed and have SS power hoses installed.

Just had my 4th remote key programmed today while making the appt., somehow my girlfriend manages to wash them regularly. . . = (

The pedal behaviour as you describe, is left with an original brake system, is mostly caused by a faulty booster . With the master brake cylinder removed from the booster (2 nuts - brake lines can stay in place) you can inspect the inner side of the booster, check for rust and water traces. If traces are present, replace.

I'll look into this tomorrow thanks for the heads up on the how to and the info.
