Bleeding Brakes

Steps for bleeding GenCoupe brakes or any production based vehicle with single master cylinder
retrieved from MBS & here's the link: Brake System Bleeding

Supplies needed:
- 2 people
- Supply of high quality brake fluid from an unopened container
- Bleed bottle (I used suction from flush machine)
- 10mm hex box end or line wrench for bleed screws on calipers (2 per caliper)

With the car on jack stands and a person sitting in the driver seat:
(There are enough threads on jacking & supporting a car with jack stands etc..)
- Place the wrench over the bleed screw on the caliper furthest from the driver
- Place the bleed hose attached to the bleed bottle over the bleed nipple with the wrench. If the caliper has two bleed screws, start at the inboard bleeder first (ours do)
- Open the bleeder
- With the bleed screw open, have the "driver" slowly depress the brake pedal to the floor. With the driver holding the pedal down, gently close the bleed screw.With the bleeder closed, the driver can release the brake pedal
- Repeat this process until the fluid coming from the caliper is clear and free of air bubbles
- For calipers with 2 bleeders, repeat this process for the outboard bleeder
- Monitor the fluid level in the reservoir and refill as necessary during the process
- When finished torque bleeders to factory recommended settings

Repeat these steps for each caliper, working towards the caliper closest to the driver. At times it is helpful to tap the caliper body with a soft mallet to release any small air bubbles trapped inside the caliper. At this point, the brake pedal should be checked for firmness and consistency. If the fluid is free of air bubbles and the pedal is still soft or spongy, there may be further issues that need to be addressed with the brake system. When finished, fill the fluid reservoir to the "full" line, but not over.

I like using a good hand vacuum pump. Easy too do with one person. The trick is to seal the threads on the bleeder screw with some paste type thread sealant.

Don't forget to bleed the clutch line as well since the clutch fluid is shared with the brake fluid.

I've never really had good luck with hand vacuum pumps. If I were to do it myself, I prefer to use a positive pressure bleeder. Easy to make by using a garden sprayer and extra brake fluid cap.

I definately did in my case, since I replaced the clutch line with KPR SS as well.
