Twas the night before New Year...

...and Rob was pulling out hairs.. I have finished working through my little list, with just one thing left to get sorted... The Bleeding Brakes.

Thanks for all the advice so far, I'm happy the brakes are as bled as they can be. All is adjusted and new. I suspect the pushrod may be the problem as suggested.

There is about 15mm of travel of the pushrod before it contacts the piston in the master cylinder. I have a Tandem booster, and a big nut master cylinder. The pushrod I have is 155mm long (and came with the booster, I had no reason to question it). Does anyone have the specs, or any idea how long they should be, or wouyld it be worth trying to source a longer one? If so, what model should I look for. Better still.. does anyone in Perth have something lying around? The car is booked to go over the pits on this Thursday, 3rd of Jan.

Cheers,
Rob

The LCGTRestoration is finished... it's on the road so time for a new handle. Look out for 71LCGTR

HAVE you checked to see is you can adjust the push rod length
THE push rod from the pedal to the master cylinder is NOT one long rod the master cylinder end is separate and can be pulled out of the booster often the end of the rod that goes into the master cylinder is adjustable, has around domed head on it takes a 5/16 or 3/8 ring spanner to unscrew it it will be tight you will need to old the shaft behind it about a 1 inch back with vice grips while you lengthen the end screw it out till you have only 2-3 mm free play between the rod and it hitting the piston in the master cylinder , when all bolted up tight..

THE other thing is this the piston in the master cylinder can differ even thou they are all the same internal and take the same rubbers ,THE HOLE in the piston can and dose vary , some were a deep hole , some were shallow and some in between , why they done this i dont know... i would say your piston in your master cylinder is a deep hole one and your push rod is for one that is not as deep or possibly for the alloy type master cylinders which seem to always have not as deep a hole type pistons..

15 MM of play. The reaction disc could have dropped out from behind the booster front push rod. That can give you about 10 to 15 mm of play. Just something else to check.
