I have been trying for about one year to get the brakes fixed on my C60 truck. The truck has a hydrovac system. When I fill the resovoir it always leaks out. Saturday I noticed the boot directly behind the brake pedal is torn and brake fluid is leaking down the wall onto the floor behind the mat. This is why I could never find the leak anywhere. Is there a valve behind this that would be leaking or is it just the boot? Appreciate any help!!
