Brakes are hard to push. No fluid to rear. Bypassed abs- I went staight from the master cly. to the rear brake line. fluid to the rear then. How do you bench test the brake by-pass valve? Or is it called the Brake comb. valve. It is hooked right to the front of the EBCM and the Brake pressure modulator valve. I have fluid going into the brake comb. valve but not coming out of the brake pressure modulator valve. I need help! Thanks for looking at this.
