There was more to it than that. Quote Link to post Share on other sites
Waldi Posted November 12, 2020 Report Share Posted November 12, 2020 If the problem was the casting, can this have resulted in sucking air in? Just curious what exactly caused the failures reported in the past which were more around leaking oil out or “no brakes left”. Anyone? Cheers, Waldi Quote Link to post Share on other sites
stuart Posted November 12, 2020 Report Share Posted November 12, 2020 There were numerous problems, tipping valve sticking, not concentrically bored, leaks around the tank, leaks back through seals, you name it it was wrong etc etc. If you search for the original thread on it the saga went on for a long time and no responsibility was ever admitted.

Waldi Posted November 12, 2020 Report Share Posted November 12, 2020 Thanks Stuart, hard to believe a manufacturer can produce such poor quality. Waldi Quote Link to post Share on other sites

Thanks, Waldi Not really as they were in genuine looking TRW boxes and looked the same as the offerings previously and since. I dont know if there was any batch numbers on the boxes at the time. New ones now seem to be OK as theres been no failures apart from yours for a few years. Stuart. Edited November 13, 2020 by stuart Quote Link to post Share on other sites
Waldi Posted November 13, 2020 Report Share Posted November 13, 2020 Thanks, mine is a reconditioned original by the way, no issues with that luckily. Waldi Quote Link to post Share on other sites
Peter Douglas Winn Posted November 13, 2020 Author Report Share Posted November 13, 2020 Steve I have 2 systems 1. Snap-on vacuum pump that sucks the fluid out of the nipple. 2. A bottle with a transparent hose and a one way valve. This was bought from a big supplier who normally sells thing only to garages. It works. The advantage of the vacuum pump is I don't have to push the pedal. I just undo the little bleed screw suck and screw it back up again. A one man job. Quote Link to post Share on other sites
JochemsTR Posted November 13, 2020 Report Share Posted November 13, 2020 I switched to Saab MCs.....but that is another story. Quote Link to post Share on other sites
Peter Douglas Winn Posted November 17, 2020 Author Report Share Posted November 17, 2020 To be on the safe side I have ordered a new MC. If the old one is OK then I have a spare. I will at the same time finished the piping. Quote Link to post Share on other sites
