resleving rear master cylinder in Oz

Hi all, does anyone in Oz know if the rear m/c can be re sleeved. Just went to the local brake centre and they said the 14mm bore is too small.

Cheers Moz

Hello & welcome Moz....

J-B Weld & drill/ream it back to 18mm may be a "possible" route to go. Prep it well prior & clean with acetone to give a good base

Thanks for that, who are J-B and are they in Oz?

Cheers

I'm sure you can get it shipped. Use the "orignal" stuff it's far better then the newer fast cure "Kwik" version.

I was quite reluctant to use J-B Weld. With the packaging making such outrageous claims, it had to be junk, right?

Well, I followed the instructions of an older-but-wiser CBXer (Dave Ditner) and used it to repair a wheel caliper piston that was badly pitted. That was back in about '95. It's still on the bike, working just fine.

One of the key things with JB Weld is temperature curing. If you can put the part in an oven and cure it at 180 degrees for 5-6 hours it improves the bond significantly.

Andddddd then....there are those non approved uses :suspect: :suspect: :suspect: :suspect: :suspect:

Issue
Aprilia Capo and 916 stock mufflers with holes where the small brackets to hold the mufflers together were removed

Fix
Mixed JB Weld with steel wool.....stuffed a bit in each hole...waited the specified time for it to dry....started the bike and let it idle for ten minutes. That was 24,000 miles ago...worked great.
