I got a bit of a fright a while ago when I put my foot on the brake and nothing happened. A few pumps of the pedal brought them back to life. For the next week there was a squeak on breaking and a light smell of burning brake oil. This was all a couple of months ago. I have not found any signs of a leak and the reservoir level is not falling.
I'm pretty sure a problem like this will not fix itself. Any ideas please?
