Richard71 Posted March 16, 2016 Report Share Posted March 16, 2016 Hello All, I've discovered I have a faulty brake servo check valve (non-return valve). The servo is an aftermarket TRW item supplied via TR Shop. I've contacted TR Shop & TRW requesting a replacement but neither can help, it seems they can only supply the valve with the servo, £100+ for a check valve and spare servo that I don't need, NO THANKS! The original valve doesn't fit the TRW servo, it's diameter is to large. Surely there must be someone supplying replacement valves, or has any forumites came across this already and found an alternative solution? Extremely grateful for any help. Regards, Richard.

John L Posted March 16, 2016 Report Share Posted March 16, 2016 Is your problem with the non return valve, or the sealing of the complete valve to the servo body? You can get a non return valve that will screw into the manifold, not too sure which car it comes from, but I'm sure somebody on here will give the details.

Alec Pringle Posted March 16, 2016 Report Share Posted March 16, 2016 The manifold non return valve for TR6/7/8, 2000/2.5, assorted MGs and Landies is ADU1402, there is a Land Rover alternative LKX100440 at less than half the price . . . . . google is your friend for suppliers.

Guest ntc Posted March 16, 2016 Report Share Posted March 16, 2016 Richard Is it push in or bayonet? Quote Link to post Share on other sites
Richard71 Posted March 16, 2016 Author Report Share Posted March 16, 2016 John, No problem with sealing, I shouldn't have said faulty, "broken" would be a more appropriate word as in it's in several pieces (probably due to bad storage on my part) and despatched to landfill/recycling a few days ago. The manifold fixing as yourself & Alec suggest is ideal but it still leaves me with nothing to connect the hose to at the servo end. Neil, It was a push-in, barbs on the valve.

Richard71 Posted March 16, 2016 Author Report Share Posted March 16, 2016 It occurred to me that I could split the servo casing and using a step drill enlarge the orifice to accommodate the original sized check valve, but, having had a look on the Buckeye Triumph website at the procedure for splitting the two halves....I don't think I'll bother, looks a nightmare of a job!

Alec Pringle Posted March 16, 2016 Report Share Posted March 16, 2016 Hi Richard, plenty of variations available . . . . https://www.google.co.uk/#q=brake+servo+non+return+valve Cheers Alec Quote Link to post Share on other sites
ed_h Posted March 16, 2016 Report Share Posted March 16, 2016 Richard-- Opening a servo that is relatively new might not be that bad. It does take a special "wrench", but that is pretty easy to make. Alternatively, you could weld a threaded bung to the hole and use an external check valve. Ed Quote Link to post Share on other sites
Richard71 Posted March 16, 2016 Author Report Share Posted March 16, 2016 Thanks again Alec, the seller would have to detail the diameter of the fitting to suit the existing grommet on my servo, none of those sellers supply such data. Quote Link to post Share on other sites
Guest ntc Posted March 16, 2016 Report Share Posted March 16, 2016 (edited) Drill the innards out of the one you have and put in a inline one, google mini sport. http://www.minispares.com/product/Classic/17H2646.aspx Edited March 16, 2016 by ntc Quote Link to post Share on other sites
Richard71 Posted March 16, 2016 Author Report Share Posted March 16, 2016 Neil, The one I had was in two or more pieces, smithereens! Quote Link to post Share on other sites
Guest ntc Posted March 16, 2016 Report Share Posted March 16, 2016 Richard Bad form from them both and then remove the servo hold upside down and use your step drill. Quote Link to post Share on other sites
Richard71 Posted March 16, 2016 Author Report Share Posted March 16, 2016 Richard Bad form from them both and then remove the servo hold upside down and use your step drill. There's no guarantee that all the swarf would be removed, far too dangerous. I think the solution would be to fit the correct size of this http://www.ebay.co.uk/itm/Plastic-90-Degree-Connectors-Joiner-Hose-Pipe-Tube-Silicone-Rubber-/200963328389?var=&hash=item2eca590985:m:mJCXfUQpYwNiEaNiHzWrP7g and the manifold mounted check valve previously suggested by Alec. Thanks to all for your helpful input. Richard. Quote Link to post Share on other sites
