///Rear disc swap\\\
I just swap out the rear brakes on my civic. I have a 97 coupe and put 01 teg rear disc on it. Well i used my same trailing arm. I hooked up everything and i bled the brakes. I started with the pass. side first and then the drivers side. But my pedel is like touching the floor. So i bled it again and the same stuff is happening. Do i have to switch out the master cylinder and boost pump?

try bleeding the front too. if that dont work crack all four of them open and keep an eye on the fluid in the reservoir (keep it full). let about 20 min pass and close them all back off. should work this is what i do when i run into bleeding issues. good luck to ya

Re: ///Rear disc swap\\\
yes it is... you are bleeding it wrong. You have to remember that the whole brake system is 1 single hydraulic system. So, air must be bled on all 4 corners. Having said that, you must also bleed them starting from the most remote caliper to the closest caliper (in relation to the master cylinder). So, bleed it in this order:
1) Rear passenger
2) Rear driver
3) Front passenger
4) Front driver
Make sure that your "method" of bleeding is proper. The way I do it is very simple and can be done without asistance.
With the brake fluid reservoir in full amount and the vehicle is raised up as horizontally even as possible:
1) after the bleed port is slightly loosened, connect a hose/tubing and submerged the other end of it in a container filled with brake fluid.... keep the hose end always submerged in the fluid. This will allow the air being bled to escape during the downstoke.... then suck fluid during the upstroke. Pump the pedal several times then tigthen the bleed port.... repeat it on all corners....constantly check the fluid level in the reservoir

I always gravity bleed for a few seconds before starting my actual bleeding. I've found that it usually bleed much quicker and I only have to repeat the bleed cycle once.
