I'm not having any brake pressure when I push the pedal in, and I put new fluids in my CRX yesterday. Another thing that my car is doing funny when I press the break in, is it is also revving the engine up a little, kind of like I am pressing on the accelerator (but I'm not). Is this my brake master cylinder? Has anyone else had any problems similar?

i have the same problem, and i was told its a problem in the brake booster, as my pedal is very firm when the car is off and quite spongy when it is on, also from what i hear shifting of components in power assisted brakes can weaken the feel of the pedal

 

The brake booster will rev the car up slightly so if u have a low rev, it won't kill ur car.

 

Bleed the brake system and do a full flush, and take off ur master cylinder and clean in it fully. U should be good then. Check if you are losing fluid. If you are check if u have a hole in a line.

 

Haha, the thing is, I have a high idle, so it does kind of hurt my car because basically when I brake it also seems to give it a little bit of a rev (like 500rpms more), but it's really noticeable.
