Does anyone know what brand rear brake master cylinder/brake assembly this is by the pictures? I just bought the bike, not a lot of information as far as the mechanical outside of the engine, and we noticed when we were replacing the clutch pack, and stepped on the rear brake so we could tighten everything up, that it appeared the rear brake master cylinder leaked a bit of fluid when we applied the rear brake.
It is completely blank of any labels, it doesn't have any markings or logos on it at all. It is on a set of aftermarket extended forward controls. I'm looking to get a rebuild kit so we can hopefully fix the leaky issue. Thanks!
For anybody who might have a similar situation and comes across this, I posted it to a few FB groups and a few people agreed it looked like the GMA Rear Brake Master Cylinder.
I ordered this GMA rebuild kit, it appears they also have another one with the top cover and maybe a different plunger/spring so we'll see if we got the right one.
There are a lot of aftermarket rear masters that look similar, PM, Accutronix, Jay Brake, GMA and more. The best thing to do is disassemble yours and measure the bore, then look for the rebuild kit...
Probably would have been better off disassembling the old one before ordering parts, but lesson learned and thank goodness companies are good about offering return policies!
This appears to be the parts that match to the master cylinder I have on my bike.
We attempted to just clean and put the old parts back in and it still seems to be weeping some fluid, so I'm ordering this new kit and sending the other one back.
