I have a lot of pedal travel of deadness - like nothing for a couple inches maybe and then the brakes apply themselves.

Its not spongy, as they work.

Current setup is;

Clio Servo
M3 Evo fronts
Compact rears
Non-abs

Any ideas?


I've been on the wiki and there is some suggestion of spaces or adjustment?


Another question is, can i get the servo off without draining it?
(might be a silly question)


Ta!

I suggest that the relevant bit of the wiki is "The brake pedal forms part of the pedal box, It is connected to the master cylinder through a pull rod, which can be adjusted to control pedal height. There's a small rubber buffer on the lowest part of the bracket that holds the brake light switch, and the rod should be shortened until the arm of the pedal all but touches this buffer.

To adjust the brake pedal, slacken off the lock nuts and turn the pull rod using a 7mm open-ended spanner on the flats near the clutch pedal to adjust, until the brake pedal only has a small bit of upwards free movement to its stop. One end of this rod has a reverse thread, so turning it changes its length.

Be careful though. If you over-tighten things, so that the pedal is touching the buffer and moving the master cylinder push rod, the brakes are likely to lock on."

The brakes on my car were awful before that adjustment.
