blubayou Posted August 23, 2019 Report Share Posted August 23, 2019 Hi all, Having had the brake master cylinder start to weep again (second time in 17 years isn't bad) I decided to replace the old Girling unit with a modern replacement which has the definite benefit to my eyes of a translucent reservoir. To complement this & save the old paintwork I have also fitted a drip tray. As you can see it fits very well apart from the hole for the boot. I didn't consider this an issue at first & have now sealed the tray to the bulkhead with mastic. The boot now obviously does not fit the hole, but then again it's an original item, probably 46 years old & didn't fit before. Any ideas? Steve.

I've got new boots. They are a bugger to fit! I've tried boiling them to soften them up, grease, oil, nothing works. I think they are just too big for the holes, I'm contemplating bathroom sealant. But, I don't need the drip tray, silicone brake fluid is wonderful stuff. Doug Link to comment Share on other sites More sharing options...
Pete Lewis Posted August 24, 2019 Report Share Posted August 24, 2019 Ive seen one with a up ended mud flap idea in front for any splash, and door bristle draft excluder around the hole for drafts. Old boots are a fiddle to get the lip located new ones are worse than hopeless Pete Link to comment Share on other sites More sharing options...
Rabbit Posted August 24, 2019 Report Share Posted August 24, 2019 When we eventually leave the EU (if ever under this lot) can we go back to proper rubber boots and Nitromoors that is stronger than cats wee etc etc and everything thats formula has been changed to suit go back to original including decent high octane petrol with NO ethanol. Now even tyre rubber from my pushbike is apparently killing 3 people worldwide a year! Link to comment Share on other sites More sharing options...

Badwolf Posted August 24, 2019 Report Share Posted August 24, 2019 The replacement master cylinder boots never seem to fit and the quality of the 'rubber' is cr*p. It is too hard and not pliable enough. It would be interesting to take a survey at a meeting/show to see how many aren't seated around the edge properly. Mine aren't, I gave that idea up very quickly. I did read an idea to fit the boot like a windscreen by putting string around the groove and pulling it through from the inside. You need to be very bendy for that.. the usual upside down, feet over the back of the seat, inspection lamp singeing your ears.... then the phone rings or the JWs come to the door to save your frazzled soul!!

blubayou Posted August 25, 2019 Author Report Share Posted August 25, 2019 Well all fitted & working now. I opened up the ally to match the original hole. Neither the original boot or a repro would fit properly. you can see the difference in length of the old & new. The old was too distorted to stay in place. I cut all of the flange off the new one except for the toe end, hoping this would dig in & hold it fairly well in place. Link to comment Share on other sites More sharing options...
blubayou Posted August 25, 2019 Author Report Share Posted August 25, 2019 As you can see it looks ok, I may try & seal the boot with mastic. Maybe another day..... Link to comment Share on other sites More sharing options...
Unkel Kunkel Posted September 11, 2019 Report Share Posted September 11, 2019 These things are a real struggle and I have never been satisfied with the fit ! With respect to originality the mere thought of this is heresy, but.. -I have wondered.. would it possible to fabricate a metal “box” for each with a removable top panel for access to the joints and be done with the darned things?

blubayou Posted May 31, 2021 Author Report Share Posted May 31, 2021 Well, the drip tray works... Master cylinder 400 miles & 21 months old. It would appear to be leaking from the joint of reservoir to cylinder. Link to comment Share on other sites More sharing options...
Adrian Posted June 2, 2021 Report Share Posted June 2, 2021 I Tried these on mine and felt they just didn't seat right or look right. But theres no denighing it captured the fluid! Link to comment Share on other sites More sharing options...

You say "drip try works", while I wonder if that brake fluid isn't getting under the washer and spreading unseen beneath the drip tray...? Link to comment Share on other sites More sharing options...
