2 Times this week, as I made hard left turn with my foot on the brake, the pedal went to the floor and I could pump it once and it would come back up. It (the brakes ) operate fine till I make similar moves again. the fluid level in the master cylinder is up to normal level. I see a bit of fluid at rear of cylinder on the booster. I cleaned the fluid off, and see no more seepage as yet. Is it possible that this could only happen on hard left turns only, has anyone ever experienced this or even heard of it happening before? I think maybe it is time for a new master cylinder. But, I was curious. I have 1978 C10 Big 10, 350cui. , TH350, 11" X 2" rear drums, Discs in the front. My brakes lines attach on the right side as you look from front of the engine compartment at the master cylinder. When I apply the brakes under normal driving conditions, if I mash a little hard, I can hear a SQUISH noise under the dash. could this be from a bad diaphram in the cylider? I had the front wheels off today to check condition of rotors and pads, everything looks new, no warpage of rotors. The rears are a different story, I need new drums, shoes and brake hardware, it all looks original back there, drums are definately out of round, they have rivet grooves very deeply imbedded in them. Only the shoes have evr been replaced ( I think ) lol. The shoes on left rear are loose on the mounting pins ( Nail through back of backing plate ) Will replace all mounting hardware. The current shoes are bonded and there are chunks of braking material missing on left side front part of shoe, shoes are worn really thin ( 3/16th.'s ) in the middle of shoe, and 1/4" on each end. Thanks for replies in advance. I didn't even know where to post this question. Sorry if it's in wrong place.........Larry BTW, my truck is 2 wheel drive, 1 wheel squeal.
