Brake problems

I started having trouble with the brakes on my 79 F-250. It started with the back brakes (specifically the right rear) occasionally locking up without too much pressure on the pedal. Now both rear wheel cylinders are leaking. I ran out of fluid in the rear reservoir and could barely stop. I pu the pedal all the way down and all it did was lock up the right rear. I think the proportioning valve might be stuck but I'm not sure. Is there anything I can do to pinpoint the problem?

How much shoe is left? Usually when you blow out the cyls the shoes got worn out and out of adjustment. If the shoes are shot it wouldn't take much to lock up the rear tire if the shoe is metal on metal.

I haven't had a chance to check the shoes but the last time it was in the shop ( 4 months ago) The mechanic said there was plenty of shoe left. When get a chance I will double check.

This problem sounds expensive.

It's time for a complete inspection of ALL part components.

I had a feeling that would be the case

The good thing is you will know everything should be "good to go" good after the repairs are done.

On the bright side, even that long list of repairs will cost you a fraction of what it would on a newer truck. Tis the beauty of the beast.
