Rodbr Posted July 15, 2019 Report Share Posted July 15, 2019 Given that the reputation of repro brake cylinders and master cylinders is not good. Does the team think it would be worth using a set of small honing stones to sort the internal bore rather than use as is? Answers on a postcard please.

BlueTR3A-5EKT Posted July 15, 2019 Report Share Posted July 15, 2019 I have seen a new repro master cylinder that was bigger than the OE bore stock size (0.750"), and that was also oval. I am unsure if honing something with those discrepancies would make good. Cheers Peter W Quote Link to post Share on other sites
Graham Posted July 15, 2019 Report Share Posted July 15, 2019 I'm sure there is a company that 're sleeves' originals but can't for the life of me remember who it is !! sure somebody will be along shortly to advise Quote Link to post Share on other sites
Rodbr Posted July 15, 2019 Author Report Share Posted July 15, 2019 I know who it is (Past Parts) but baulk at over £100 to re-sleeve something that should work out of the box. Hi peter, I get what you are saying but perhaps honing an original has merit. Quote Link to post Share on other sites
Bfg Posted July 15, 2019 Report Share Posted July 15, 2019 Seems to me logical to check the originals first for corrosion, scoring and wear. That ought to answer whether its feasible to reuse with new seals or whether you need to go shopping. I had to replace the seals in the master cylinder of my '74 Citroen Ami-super, and did that without needing to hone the bore. My bigger concern finding rubber parts for this odd-ball car which weren't also 45 years old.! Brake cylinders and master cylinders on most Brit cars were almost certainly a universal item ..used on a variety of different marques / models. So new-old-stock may still be an option, if you just know where to look. Quote Link to post Share on other sites
RogerH Posted July 15, 2019 Report Share Posted July 15, 2019 Hi Rod, if you find OEM or repro parts that are no good then report them back to the supplier and possibly forward a PQI form for us to investigate. https://www.tr-register.co.uk/pqi They should work out of the box.
