Too much brake pedal play.

Post by terry23 » Thu Aug 16, 2007 3:03 pm

My brake pedal has retreated over the summer and has more play than normal. I've adjusted all the brake pads and bled the brakes but play remains the same. Muir warns about adjusting the master cylinder push rod so I haven't done anyting with that.
No fluid leaks at all.
Any suggestions.

I would suspect your hoses. How old are they?

Was this a gradual thing or did it happen all at once?

Retreated??

The play is the distance the pedal travels before the pushrod hits the
piston in the M/C. If that is the play which has increased, then the
pedal stop on the pan is moving/bending.

It has happened gradually over the summer. The retreat I mentioned is the distance from the full upward position to more than half way to the floorboard when I originally had very little movement before braking began. My brake hoses are not new but do not show any sign of cracks or leaking. Brake function is good but I don't think there should be so much travel in the pedal before it starts.

Try this experiment, just as a test:

Tighten all the star wheel adjusters so tight that the wheel won't spin.
Check the pedal travel.

If the pedal is once again high and hard, the problem is caused
by excess clearance betwen shoes and drum or, maybe, misassembled
parts.

If the pedal travel is still too great, I would suspect the Master Cylinder.

(Back the adjusters off after the test is over...)
