Bulldog-BT1100

Finding it hard to find a repair kit for the rear brake master cylinder, I know it's made by Brembo and must be used on other bikes. Anyone know which bikes, I've heard that some BMW bikes of the same age did.

In March we had already a similar topic:

In my opinion this Brembo part looks similar despite the colour:

Rainer did not report if he was successful with that part but if you take a look at the dimensions in the PDF in the link above it should fit.
And there is no repair kit for that master cylinder either. You can buy only the complete unit.

Hello, of you look to the brake cylinder there must be a number on the under site. This is normally the diameter of the cylinder. Then look at Brembo rep kit for brake cylinder rear brake.
Hope I could help

Thanks for the swift reply, Riedrider, that PDF is useful thanks. MK3103, I've tried googling the number on the cylinder to no avail.

There could be a 2.nd solution to find out which brake cylinder it is. You can measure the diameter of the cylinder. And if you have separated the inner parts you may have a look to this website.

They have repkits for several hand and foot pumps. So they have a telephone number you can use for clearing.

I dont think that there is a repair kit for this special master cylinder.
Stein-Dinse who offers only the complete unit has repair kits for many other Brembo cylinders but not for this one.
And the PDF data sheet shows only the pipe fitting and boot as available spare parts...

Hello Günter, I don't think that there is something special about the rear brake pump. If you look to the website of my former post you will see that the repair kits are for several rear brake pumps.
So there is a chance to get a repair kit. Why shouldn't he take the chance?

Hello Michael, he needs a repair kit for a PS13 with 13 mm piston diameter. And there is nothing available on your website.
But you can buy the complete unit like at Stein-Dinse:

Ok, the parameters were not publicated. Nice that you have them and gave us the information. So you're right. Buying the new one is an option.

Especially for that price. When you buy it from Yamaha you will get it with connecting rod but for more than double the price:

By the way: I drove this morning through Büttelborn on my way to Helvetia Park

Oh yes, that can happen. If you want we can meet. Send me a PM

You got PM

The PDF was very useful as it gave me some info to go on. Googling I came to the conclusion that no Brembro repair kits are available. The non-yamaha one is fairly priced anyway. Thanks for your help.

I don't know how exactly the technical inspection works in England. Maybe a Nissin brake pump will you work too.

Feedback from Rainer with pictures: the Brembo cylinder from Stein-Dinse works:
