Hello everyone. I haven't been on here in a while. My '49 3100 has been running pretty good until recently. Battery went bad back in late November, so with winter coming on, I thought I would wait until warmer weather to invest in a new battery. Bought a new battery Monday and got her fired up. Was going to run a short errand and when I started out of the shop and hit the brakes, the pedal went to the floor. I replaced the master cylinder with a new one about 18 months ago, bled and adjusted the brakes and had a good full pedal when the truck was parked back in November. I checked the master cylinder, and sure enough, bone dry empty. I checked around all the wheels, but I couldn't see any signs of wheel cylinder leakage. I did see what looked to be a little brake fluid on the left front tire on the inside. I'm thinking the wheel cylinder is probably bad on at least that wheel.

I've never changed a wheel cylinder before on one of these old trucks, but I guess it's time to learn how. Can anyone direct me to a resource that will walk me through the process? Also, should I go ahead and bite the bullet and replace all four wheel cylinders while I'm at it? Where's the best place to buy new wheel cylinders?

Thanks in advance,
Darrell

I would suggest doing all the wheel cylinders and the three rubber lines. I would also look at the hard lines very carefully. You will need a tool for installing the brake springs. Also it would be a good idea to leave one side together until the other side is done. That way you can compare the two.
