2002 idle speed/brake question
Hi. My 2002 has long pedal travel and a soft feel in spite of new pads/master cylinder. This is compounded by an 800 RPM idle speed that the dealer says is "in the computer" and cannot be lowered. Any solutions to lowering the idle speed, shortening the pedal travel, firming up the brakes? Thanks. Greg Polito

The idle speed is specified in the service manual as 750 rpm ± 50 rpm, so 800 rpm is not abnormal. You might have some air bubbles in the lines following a master cylinder swap, I would ensure that the brakes have been bled thoroughly and see if that helps. However, the problem might be with another component of the braking system, perhaps in the ABS modulator, as there isn't much else that would produce such symptoms.

If you DIY bleed, start at the wheel farthest from the master cylinder (passenger rear), then work your way to the next closest wheel (driver's rear), etc. Use Dot 4 rated fluid with the higher boiling point. High idle could be a symptom of throttle body and mass air flow sensor cleaning needed as well. Brake bleeding machine does a better job of flushing brake lines than the manual old-fashioned method IMO.

Honestly, the car's braking ability felt like new. Keeping in mind that I changed pads and had front rotors re-finished. Still braking smooth as silk.
