aight guys i just swapped out my stock CX master cylindar and brake booster to a GSR master cylindar and brake booster...now it doesnt seem like its building pressure or even gettin brake fluid into the lines...i had to move my stock line to the other side and flare it and put the GSR fitting on due to the stock CX mc having the lines on one side and the GSR on both sides. i dont see any leaks but for some reason i dont think its even getting fluid into the lines. i filled up the mc cup and it doesnt even drain down when i pump the brakes...the brakes feel stiff but it doenst even have a stopping point like its supposed to...we tried to bleed them but it wouldnt even get any fluid into the lines...anyone encounter this problem?

 

you have to bleed the master cylinder first. you loosen the two lines going to the prop valve. then start pumping and let the fluid squirt out. do tat until there is no bubbles rising from the master cylinder.

here's a link to my brake swap how to - https://honda-tech.com/zerothread?id=820484

i almost forgot to do this too.

 

master cylinder may be bad.
