Brake pedal too low
My brake pedal at rest is about 1" lower than the clutch pedal on my '78 F100 2x4 (3 on tree). I keep adjusting the brake light switch because the play seems to keep causing the limit switch to move, thus brake lights stay on (switch not loose or worn).
Could it be that one or both of the return springs in the master cylinder are busted or shot, so that the push rod is not returning all the way? The brakes seem to work ok, though some heavy pushing is required, and the pedal goes down about half way (despite new shoes).
- The bushing on the clutch is fine.
- Rear brakes are adjusted - I put in new shoes, turned the drums, bled and adjusted so there is a slight drag.
- I have no booster - just plain old master cylinder.
Should I start pulling apart the master cylinder looking for worn or busted springs?
