Based off my other post regarding brake problems with a 1990 Honda CRX Si I am investigating the brake performance to identify the failure mode. Or more importantly verify that there was a change or improvement after replacing a part.

I am curious if someone knows the optimal or normal un-boosted and/or booster brake pressure on a four wheel disc Honda CRX Si? I have a brake pressure gauge and have measure my un-booster pressure at around 650 PSI stomping on the pedal. I have seen reference to needing 1200-1400 booster pressure to stop a car but this was a generic reference.

A friend found a chart in his manual that listed the brake pressure balance front to rear which including what peak values he should be seeing. I do not have my manual on me at this moment so I am not sure if it is even in there.

Thought I would ask here to see if someone has some data regarding the CRX brake system.

Did a search and did not easily see a topic on the subject so I made a post for future references.
