[T3] Brake Pedal Sticking...

[Dave Hall]

It's most likely in the pedal shaft.  The old Beetle had a grease point for
it, but I don't think the Type 3 does.  

Try some spray grease first, which will penetrate and lubricate the shaft.
Check the return spring is there and working OK.  

The push-rod isn't held in the master cylinder, so even if something funny
was happening with that, it wouldn't stop the pedal returning.

I suppose if the rubber boot was caught, or torn, it might be jamming the
push-rod somehow, but you should find that when looking at the pedal
cluster.  You will need to remove the plate that covers the area.

Maybe you've got something on the floor behind there that is jamming the
pedal.


It's just possible the compensation port(s) are blocked and not allowing
fluid to refill the master cylinder.  The pedal should still return under
spring action, so I'm sure  it's not the reason for the sticking pedal, but
it can certainly cause brakes to bind, as can old hoses.

Sqbk 71 Std FI--

Twice or so yesterday, the brake pedal stuck in down position....as if some
suction was holding it. That didn't happen again right away, but a few miles
later (in stop-and-go city traffic).

I haven't crawled under yet to look for suspicious things, but did plan to
put a nicely cleaned-up and re-cut rotor on the front right...where some
braking issues seem to be happening. That is...in heavy-breaking moments,
there's some rough wobbling.   Last week or so, when checking out the area,
the caliper seemed to be ok (both pistons were able to be pushed back in
with a flat pry bar without undue effort).  And...we discussed the Piston
Retainer Plates here.

But...re/ the brake pedal sticking.  Q.  Could that be connected to that
front right rotor and caliper?  Or, can a sticking pedal only be caused by
something funny in Master Cylinder?
