Tim Hunt Posted May 14, 2022 Share Posted May 14, 2022 For many years I was plagued by a rust coloured corrosion on the master cylinder threads, which required cleaning off at regular intervals. Some time ago I replaced the clutch m/c cap with a plastic one and this solved the problem. These smaller plastic caps are widely available but until just now I had been unable to find a similar plastic replacement for the larger brake m/c cap of approx 63mm i.d.(original alloy cap is Girling part no.510844). I received a tip off (thanks to Kevin Fielder 'Box of Bits') that such a cap is now available from Upgrade Motorsport (see link below) and duly ordered one for the princley sum of £4.95 (note that a replacement alloy cap is currently £20 plus delivery from Moss). I can report that the cap is vented and fitted perfectly as a direct replacement for 510844. Hopefully my days of regularly cleaning the brown mess off cylinders and caps are now over. The plastic reservoir caps in my car would probably offend the purists but then so would much else, it's never going to be a concours candidate - i enjoy driving it too much. https://www.amazon.co.uk/Upgrade-Motorsport-GIRLING-Brake-Reservoir/dp/B08P3MMXVV 3 Quote Link to comment Share on other sites More sharing options...
Ben Hutchings Posted May 14, 2022 Share Posted May 14, 2022 Ah Tim! This is brilliant, I searched high and low for a poly one for large Girling MCs long ago and gave up. I too have a smaller one (mini fit with level sensor) already. I checked the Amazon link, and they had gone up a couple quid. Searched for the actual website and just bought one on there for just under £4 delivered: https://www.upgrademotorsport.co.uk/product-page/girling-type-brake-fluid-reservoir-cap-motorsport-classic-car-4x4-uk-seller Will report back re fit. Thanks for the tip! Quote Link to comment Share on other sites More sharing options...
Tim Hunt Posted May 15, 2022 Author Share Posted May 15, 2022 Thanks for telling me I did 95 pence in cold blood Ben! But seriously, I'm glad I was able to help you out. Tim Quote Link to comment Share on other sites More sharing options...

Tim Hah, sorry. I just didn’t want anyone else to pay what Amazon are asking now. They probably have it on the automatic pricing thing based on clicks and interest.

Tim Hunt Posted May 15, 2022 Author Share Posted May 15, 2022 You did well Ben. Out of interest I just now looked on the Upgrade Motorsport site and found the cap at £6.36 with free delivery, as attached screen shot. Tim Quote Link to comment Share on other sites More sharing options...
Ben Hutchings Posted May 16, 2022 Share Posted May 16, 2022 Ah well in that case they must have put price up following orders for it. Business I guess... Quote Link to comment Share on other sites More sharing options...
Hogie Posted May 16, 2022 Share Posted May 16, 2022 Hi Tim, I ordered two yesterday for a total of £7.92 from Upgrade MS. This inflation lark is quite dramatic. Roger Quote Link to comment Share on other sites More sharing options...
Tim Hunt Posted May 17, 2022 Author Share Posted May 17, 2022 I make that £3.96 each Roger and if it included delivery that's the same price Ben paid. It's a minefield out there! All things considered though I wasn't unhappy to solve a longstanding problem for just £4.95. Tim Quote Link to comment Share on other sites More sharing options...
Ben Hutchings Posted May 17, 2022 Share Posted May 17, 2022 Honestly I'd have paid a tenner, it's always such a pain getting the alloy one off, I think every time I'm going to snap the main body/pedestal. I'd quite like to modify it to include the level warning switch from a mini brake MC (GRK6009 / AEU1796), then wire both MCs to a little warning light. Just because 🙂 Quote Link to comment Share on other sites More sharing options...
Ben Hutchings Posted May 21, 2022 Share Posted May 21, 2022 My plastic cap arrived today, which is really good because the old one was so stuck on I had to cut it off with some snips! Quote Link to comment Share on other sites More sharing options...
