What’s the difference?

Postby Limey01 » Wed Dec 06, 2017 9:18 pm

What’s the difference between a 79/80 rear brake master cylinder and a 81/82 rear brake master cylinder? Oredered the wrong rebuild kit and want to know if it will still work.

They look physically the same but the internal parts are different. Never knew what the actual difference in the body is, maybe none, but the rebuild kits are certainly different and I would not try to use the early kit in the late m/c.

Guess I’ll have to send it back and order the right one. Thanks Dave.

Send it back?
Sounds to me like the perfect excuse to buy an early model CBX.

Maybe I can start with a rear master cylinder and slowly accumulate the whole bike.

strange how that works I've got the bits and pieces of RD 350 to rebuild around...seems simpler to buy complete bike and just add my bits to...
CBX a work in progress, still improving...GS1150EFE completed and awaiting modifications.....RD350, remnants in boxes scattered throughout the garage

I’ve already got more than enough of those projects around here including most of a ‘69 BSA Spifire, most of a ‘71 Bonneville and most of a ‘59 MK 2 Jag.

The problem is, "most of" is cheap. "The rest of" gets expensive. :o

Either garage is too small or we have too many bikes. Or Momma's car needs to go outside.

The Jag is my bugbear. It is such a beautiful car when done right and worth a lot of money. Had shoulder surgery a couple of years ago and while recovering started a spread sheet on the rebuild cost. Interior kit, (seat covers, carpet, door panels, head liner, etc.) $8,000. Replacement crankshaft (mine is already ground to the minimum), with bearings, $3,000. Bodywork and paint job, $10,000. By the time I get into brakes, suspension, interior woodwork, chrome, would like to put A/C in it, wire wheels I gotta have, I’m looking at $50,000 to get this thing on the road. Good news is if I can do it the value of the car is probably half that again. It could possibly be the only vehicle I’ve ever restored that might actually be worth more than I spent on it, that is, of course, if you don’t include my labor.

Actually I do have one vehicle that I rebuilt about twenty years ago that is probably worth more than I put into it, but it wasn’t at the time, and that is my 1970 Triumph Bonneville. The price is starting to go crazy on those.
