I’ve got a 1937 Dodge pickup mounted on an S10 frame with a 350 SBC/350 turbo that I started driving last year. The frame has the original S10 suspension and brakes Disc/Drum with an aftermarket under the floor pedal assembly with a 7” dual booster and a corvette style master cylinder.

It’s drives great but the brakes weren’t what I wanted so I replaced the drum rear end with a 2WD Blazer disc, during all the changes I also replaced the 7” dual booster with an 8” dual. Shortly after all these changes I started having random problems with the front disc dragging slightly. All the steel and rubber brake lines are new and it’s got 2 lb residual check valves on front and rear. I checked everything from the pedal assembly to the calipers and could not find anything wrong, I ended up replacing the master cylinder and front calipers with no fix. A few weeks ago I put the 7” booster back on and the problem went away. I’ve never had a booster with this problem, even though the pedal was retracting completely the second stage of the booster would stick and not retract completely especially when it got to operating temperature.

I'd contacted the company that sold me the booster and their tech said there's no way it was the booster.

The 8" booster was purchased off ebay from "gonefishing69", their customer service is the worst I've dealt with ever! I've called them several times about the problem and they finally agreed to sell me another booster for $30.00, they stated that "several people were sending them boosters from salvage yards for refunds/returns”. Even though I had proof of purchase they would not replace the booster even though it's only been 4 months, the problems actually started about five weeks after receiving it. I don’t appreciate being called a thief, this has cost me over 200.00 for the MC/calipers and a new 8” dual booster, not to mention all the labor.

I do not recommend purchasing any items from "gonefishing69" on ebay.
