I have read up all I can find on upgrading the brakes on my 1993 mk1 clipper. Standard 239 mm front disk and rear drums.
I have acquired a 9" mk2 16v servo plus a 22. mm master cylinder and am ready to reinstall.
My question is regarding the two rear brake resistor valves screwed into the original master cylinder. Part numbers thereon:
1292G on one and 127G2 and a 2 on its side on the other
Other markings are 3 arrow down and 35. Like 3v35.
After significant searching, I have been unable to find anything with similar part numbers but have seen mention of mk 1 rear brake restrictor valves needed for 19.8 mm master cylinders.
I have also seen mention of restrictors being required when upgrading to rear disks, to stop locking up. As at present, still using drums but upsizing to 22.2 cylinder do I reuse the restrictors, or not?
Another point for anyone attempting to remove the Clovis pin on the linkage, I had nowhere seen mention of the type of locking mechanism spring clip on the pin.
This needs to be sprung open to remove, easy if you know what it is but being so well hidden and working by touch, this knowledge may help someone. To replace, pushing a small Allen key in to keep it open helps considerably, easy to pull out after fitting.
Another question though is, where is the felt washer supposed to be fitted.

Question about braking system.
I fitted a new mechanical fuel pump and after that it kept cutting out under acceleration. As with you the return was taking it back before the carb could get at it. I was told to try a welding tip but I didn't. so I did away with it even then .and had no issues either with the pierburg or the Weber. Although the Weber is miles better .got it dynod the other day 106.9bhp .not bad for a 29 year old car with the original engine .that came with 88bhp from the factory. So no issues mate at all.also fitted braided stainless steel hose front to back too want expensive about £8 per metre only needed 3 metres from McGill motorsport…

The concern I had about removing the return is over feeling, I thought the carb may flood if the fuel can't go anywhere, seems like it's not an issue given your success.
106bhp, very impressive, nearly a gti

I sort of assumed that given these cars have a mech fuel pump that a return is still needed, I'll deffo try temporarily capping the return and see what happens, thanks for the info, really appreciated.
