car:
93 civic EX 1.6 VTEC
History:
recently changed out the master cylinder due to the brake pad would hitting the floor board.

current:
I can drive the car for a few miles but then the front brakes begin to lock up. If I let the car set for an hour or two and then can drive it again for a few more miles. the locking up is on both front tires.

checked:
I don't think it's the booster push rod since the car will drive for a bit before locking up
I know the master cylinder is still good since I took off the brake lines and checked for fluid squirting out

Thoughts:
I've replaced a lot of fluid butI just noticed the ABS resevoir is the the color of maple syrup, I plan on flushing the brake lines tomorrow.
Possible pinched or broken brake line, but don't know how to figure out which hose.

Other thoughts. Could this be caused by something else? I am not considering the prop valve since from what I've read the chances of that going bad are very slim

Any and all help I can get with this will be greatly appreciated.

OP check the caliper slide pins and make sure they aren't seized.

 

Yes. I still say that the push rod is not adjusted properly.
