master cylinder rebuilder? north america

PostPost by: mini64 » Wed Sep 22, 2021 2:14 am

Who rebuilds master cylinders? I have a tandem I've given up on. new kit in it after doing the honing with 600 grit paper wrapped around a wood dowel in the drill trick. Main piston hangs up most of the time, i think the secondary is stuck as well as it doesnt pump when i bench bleed. which is weird as it seems to slip in too easily. maybe its the only one that is stuck as the primary hangs about 1/4" from full out. do i just need to hone better? would like to send it off to someone.

I think it worked very well, remember you’ve likely increased bore size.

I used White Post Restorations for an Alfa MC many years ago with no complaints: https://whitepost.com/

After having zero luck with the tool shown in H2O's post I sent my tandem to someplace in CA that I can't remember the name of where they sleeved it with stainless steel. Took forever but really nice job.

I've used Power Brake Exchange on two masters and a servo; they have two locations in California.

Everyone, thanks for the help on this. For the record, Whitepost said $225 and apple said $365. Both sleeve and guarantee.

best thing you can do for your old master. It will last forever with a stainless sleeve.
