Hi guys. Anybody know where in Sydney who would repair or resleeve these canisters
Have an 850 and mine are steel looking canisters. Took them off and noticed some fluid
at the bottom of one of them. Any recommendations

Thanks

Cheaper of just buying new to be honest

Where are you buying your kits from??

Kits are around $25-$30. A new tin tank master cylinder is $200. If you're not a stickler for originality then new plastic ones are $120 or so.

I would definitely give it a go with a kit. It's not rocket science but for the brake one, yeah I guess it's a safety issue if you completely stuff it up. Take pictures dismantling, put it back the way it came apart. Lego Technic is 100 times more difficult tbh

PS. If you decide to chuck your tin ones out let me know :wink:

Just check the bores first before doing anything.
If there is no rust, major scratches or lip then give them a quick hone and throw some new seals at them.
I have done dozens of master cylinders and only needed a resleeve twice.
You can make a simple hone with some wet and dry sandpaper and a piece of dowel.

As said, if not pitted, a quick hone and seals will fix it. Same goes for clutch slave cylinders.
I have NEVER bought a new MC or clutch slave cylinder for my cars in over 50 years of Mini-ing. :)

stainless sleaving is the go, last for way way way longer than originals,
& the new chinese cyls are not a patch on the old ones once re-sleaved :-)

In the good old days we used to sleeve them with brass. Much easier to work with than SS, it lasted well too.
