For those of you following the brake problem (excess pedal travel) on my '57
MGA with MGB front discs, here is an update.
Over the weekend:
Replaced front wheel bearings
Replaced rotors
Replaced pads
Replaced caliper seals
Replaced brake hoses
Replaced MC cover with larger volume late MGA type cover
Bled through 2 bottles brake fluid
Pressurized (2x4 wedged on pedal method) for 2 hours, checked for leaks,
found none
The result? No change. Pedal still travels about half way before becoming
firm.
Previously I replaced rubber/seals in the master cylinder, clutch slave
cylinder, and rear drum brake cylinders. At this point I think it must come
down to the master cylinder. So, I pulled the master cylinder again and I
plan to send it off to Apple for a rebuild.
I'll give another update after the MC rebuild.
