My '65 FB has been sitting up for several years. I replaced the rotors, bearingsand pads but was hoping to hold off on the calipers. When I opened the master cylinder it was bone dry and I cannot get any fluid out of the bleeders (after adding fluid). Any idea where to start? It sounds like the master cylinder to me but what do I know. Do I just replace everything?

 

For the cost of a new M/C I would start with a new one whether you need it or not,,,, and you probably do.

Once installed I would disconnect the lines from the calipers and/or wheel cylinders and bleed the system until the fluid runs clear.

Inspect your hoses carefully for dry rot, cuts, rubs, etc. Replace if in doubt.

Then re-attach lines, bleed, and check caliper pistons and/or wheel cylinders for leaks etc., repair/replace as needed.... If one wheel is bad, rebuild or replace the other 3.

All of this is really kind of cheap and well worth the effort if there is a possibility that you may have some issues.

 

I would have to say that you really need to open the calipers and wheel cylinders and inspect them

Brake fluid absorbs water(hydroscopic). Wheel cylinders and calipers can rust on the inside, especially when they have been sitting for years. Been there, done that.

I replaced everything except the wheel cylinders. It still would not stop. Finally cracked the wheel cylinders and they were amazingly rusted. Replaced all four and the pedal pressure was reduced by half and it stops fine.

 

Thanks for the info. I just ordered the calipers, master cylinder and hoses. Speaking of the hoses, is there any secret to getting them loose from the hard lines?

cut the hose in half so you can use a box end wrench it will grip 10 million times better than a line wrench make sue to spray them with some liquid wrench a day in advance
