Michael Mckiernan Posted October 22, 2021 Report Share Posted October 22, 2021 My TRW Master Cyl had a slightly thinner mounting flange , this closed the gap up on the servo push rod and as the brakes got hot the front brakes jammed on Lots of stuff on here about M/C faults , whats your problem.

spiro Posted October 22, 2021 Author Report Share Posted October 22, 2021 My lastest issue is the plunger jaming fully on when I went to bleed and will not return, as well as the issue of having to adjust the servo rod to stop brakes binding, on two other TR's.

Same here, the piston went in but didn't return. I had to send it back. Quote Link to post Share on other sites
stuart Posted October 22, 2021 Report Share Posted October 22, 2021 FWIW and its bound to upset a few but TRW wont accept for return as being faulty no matter what if theyve been used with Silicon fluid. Stuart. Quote Link to post Share on other sites
Keith66 Posted October 22, 2021 Report Share Posted October 22, 2021 Stuart, interesting. Do they say that is because they think that is a contributory factor or just looking for a get out? Always tended to prefer parts from someone you've heard of rather than a generic Chinese part. Though who knows where they are actaully made, the assumption is they've got a name to protect.

harlequin Posted October 22, 2021 Report Share Posted October 22, 2021 If you have an old worn original master cylinder send it off to Past Parts https://www.pastparts.co.uk/ it will come back like new and ready for another 40 years. I have no connection to the company just a happy customer George Quote Link to post Share on other sites

I've found over the years that repro parts might look the same but often just won't work. Quote Link to post Share on other sites
