Brake Performance

Had some problems with poor brake performance and a spongy pedal. Bled all of the brakes and found a lot of air in the front brakes along with the rear.

On the rear I found that when I press the brake pedal and lift off bubbles pass back into the reservoir and sucks air into the system. Leon had a similar issue with his car and he sorted the problem by changing the master cylinder. As I had a spare 0.75 master cylinder that I didn't use for the clutch, I decided to swap it over. 

This worked a treat and the bubbles stopped. I then bled the rear brakes by removing the rear callipers and rotating them so that the bleed nipple faces upwards. Then re fitted the caliper.

For the fronts I bled each side to remove the air. Once complete the pedal felt a lot firmer.
