90 integra ls brake problem

[jdm eg6]

rpm gauge goes up to almost 2k rpm and goes back to normal when i let off the brake. also brake pedal gets hard, and its hard to stop the car..

i already try bleeding the brakes. but it keeps doing the same thing :thinking:

thanks in advanced

What is the idle like?

the idle is under 1k rpm but when i hold the brake pedal it jumps to 2k rpm and the brake pedal gets hard.. also when the driving the car its hard to come to a stop

brake booster going out maybe?

most likely that's what's causing the problem

most likely that's what's causing the problem or piston in one of the calipers is stuck:thinking:

please check you brake air line and check valve going from the booster to the intake manifold. also check the fitting on the intake manifold to make sure the fitting has not come loose or kinked. more than likely its the booster IMO. Hoope this helps sir
