how does a pushrod to a brake's master cylinder change position?
 

'92 Honda Accord LX whereby the front brakes aren't releasing properly. I've changed the MC as
it was leaking onto the braker booster outer shell. The brake booster shows no sign of fluid
internally with the MC removed. I have minimal freeplay between the brake pedal & the back of
the pushrod - I move the pedal ~ 3mm before contact with the pushrod. It appears from reading
tegger's info I may need to adjust the pushrod - how could it suddenly change when it is locked
in place and been functioning properly for years?

TIA, Ross

All master cylinders are NOT created equal...

I agree - seems to be a reasonable possibility, although I'm surprised both sides would stick at
the same time. Would like to have some best guess opinions before I start swapping out more
parts. Neither is leaking and the left front is grabbing more than the right.

This fact would apply to a MC/pushrod working fine before a change and then malfunctioning
after. In my case the problem started suddenly before any work was done. I then started looking
carefully as to why - which is when I saw leakage from the MC and replaced it - problem still
exists so now I'm trying to guess at what the next cause may be. I am about to adjust the
pushrod to see if a change in functionality occurs. Any other guesses appreciated.

I move the brake pedal slightly to make contact with the pushrod and then move the pushrod ~5mm
easily - with no resistance - before it contacts the MC. This I am confident of. No adjustment
needed as I see it.

Haynes manual - Honda Accord 1990 thru 1993 All models indicates:
Dragging brakes
1. Incorrect adjustment of brake light switch
2. Master cylinder pistons not returning correctly
3. Restricted brake lines or hoses
4. Incorrect parking brake adjustment

1. I don't believe it is this as it visually appears to function ok and has not been touched to
become misadjusted.
2. Replaced MC - bench bled prior to install.
3. Bled all wheel cylinders to replace all old brake fluid in the system with no noticeable
problem of fluid movement through the lines.
4. Parking brake applies to rear brakes - my problem is definitely on the front.
