So I start of with a really spongy pedal......Bleed the brakes and find a few bubbles in the rear calipers. The brakes are fine then and function as they should. 3 weeks later the pedal is spongy again! So again I bleed the brakes and the rears have a few bubbles in there!
i checked for fluid leaks and cant see any, checked the vacuum etc....ANYONE got any ideas please.?
