I did my conversion using 99 Civic Si parts. Rear trailer arms, calipers and e-brake cables off of a 92 Si hatch. My car is a 92 Civic CX hatch. Everything fits and bolts up. I bled the brakes but I can only get a little pressure on the peddle. Not enough to stop the car? When the car is off, I get full pressure though and the brake peddle pumps all the way up. What am I missing? Thanks.
