Questions about brakes on a 1969 k5 4x4

[draggin49]

Just picked up a 69 k5 blazer 4x4 . Took it for a drive , runs great , but the brakes are awful to the point of dangerous. Barely any stopping power and don’t engage till pedal damn near is touching the floor.The booster on it is stamped remanufactured , so I’m guessing the master cylinder is as well . Just debating on if I should even bother going through messing with this setup or just replace it with a fresh one . If I replace it I want to use something that will be a direct replacement for what’s in there and not require a bunch of other changes or mount location etc .

Best to pull each wheel/ brake drum and check condition, wheel cylinders brake pads etc. Decent replacement booster and master cylinder are probably not easy to find....nice looking Blazer BTW.

Thanks for the input I will take it by my buddies shop and we can pull each wheel and assess how things look. I figured an original brake /booster in good shape would be super hard to find so I can live with a reproduction unit if I can find one that’s just like the one in there so it’s an easy swap . Appreciate the compliment on the blazer ! I had been wanting a mostly original one to daily drive , and this one popped up . It’s a solid vehicle overall , no major rust anywhere and original paint is weathered but presentable .

Some things should not be kept original especially drum brakes if you plan on driving this on public roads. Do a disc swap so you can actually stop like modern cars.

There were a couple of things that I absolutely hated about driving my 1970 Blazer. One was the accelerator pedal that would fall off if you looked at it cross eyed, and the other was the front drum brakes. The braking effectiveness was mediocre at best, and more often times than not the thing would pull to either side. During the restoration, I have addressed both. Both designs were updated to 1971/72. Should not be hard to convert it over. The parts are still plentiful and will solve your poor braking.
