Really Bizarre Brake problem
Right - got the SLS back on and bled last night no worries.
So, me and my pal decided to do the rear brakes as well - the system at the back was empty, with fluid up as far as where the front-rear pipe turns up into the axle tunnel. So.... We spent approx 40mins bleeding the system - plenty of air coming through - but no fluid?!?! And it wasn't drawing any fluid off from the reservoir! And it wasn't leaking anywhere Totally stumped me and my mate (both experienced driveway mechanics) Any ideas anyone? The only thing I could think of was the reservoir/master cylinder seal gone and its drawing air in? |

Had that once on another make of car. The master cylinder piston for the rear lines had partially disintegrated and was plugging the line to the rear brakes. Try disconnecting the rear brake lines from the master cylinder and have an assistant slightly depress the pedal until brake fluid squirts out. If none squirts out - have the master cylinder rebuilt or replaced. If ample fluid squirts out, undo the rear brake lines at the wheels and pressure flush them from the front of the car with high pressure air to remove the obstruction. My gut feeling is the master cylinder has failed. Cars can be fun - can't they? Cheers:p :p :p

I had a similar problem on an old car. We finally figured out that the problem was old flexible brake lines. The interior had simply collapsed and shut off brake fluid flow.
What was weird was it happened to both rear lines. Never had seen that happen before. We compared the replacement (OEM) lines to the old ones and determined that the failed ones were not Mercedes brand. They were so bad we could almost break them in half with our hands. Haasman
