Start with the basics. Do a visual inspection of all the hard lines and flex
lines for leaks. Check the pedal linkages to the master cylinder (the pin fell
out of my clutch pedal on the TR3 and I thought I lost the clutch - quick fix,
however). Try bleeding the brakes. Check the rear brake adjusters.
Since it is a TR4 you have a single circuit braking system. If you had some
braking you did not have a catastrophic hydraulic failure but you may have
minor leaks that my not be immediately apparent but a closer inspection may
reveal a problem.

Subject: [TR] No brakes, 64 TR4
Haven't driven the TR4 in a few years other than an occasional trip around the
block every 6 months or so. Last weekend I started it and drove it up the hill
to the stop sign. Uh oh, no brakes, (maybe 25% stopping power). Was able to
coast down the hill using the e-brake with a little assist from the pedal.
When I had started it, the brakes felt firm. I had pumped them a couple times
to make sure they worked. I might have been a little over zealous and may have
felt a pop or a snap on the last pump. I don't drive the car enough to have a
feel for it anymore. But now the pedal isn't as firm.
Fluid reservoir was fine, maybe 3/4" low. I rebuilt the master cylinder years
ago and changed to silicon fluid.
Can anyone steer me in the right direction for a diagnosis? I was thinking
broken spring in the master cylinder, but Moss doesn't list one, not even in
the rebuild kit, so must not be a common failure. Could I have pushed the
little rubber plungers in the master cylinder past their stop point?
