Karasawa Drum Brake

ConsLack of fitting instructions
ProsIt does the job.
Bought this specifically for a two week trip to the Vivarais/Causse areas of France in September. It was rather fiddly to fit, lacking any clear instructions, but I got there eventually. I'd been caught out a couple of years ago with tandem/trailer and only two rim brakes which resulted in walking down most long descents. This did not please the stoker. But the Chinese brake proved invaluable and using a combination of all three brakes (2 X XTR + drum), we were able to descend slowly/safely, all the hills encountered. Admittedly didn't have a trailer this time, just four panniers. It did squeak occasionally, but what brake doesn't?

ConsSlightly less pretty.
ProsReadily available.
I was nervous that being a generic Chinese product this may be inferior in some way to the renowned but obsolete Arai product. Although it appears less swich and has a chromed rather than matt black finish it seems to me to do a fine job, without any noticeable fade or other problems that I worried over.

So far maintenance free after a couple of months use on average English roads. Hopeful it should have a long life and no problem with spares or replacement parts!

Do you have a Safety Brake for my old Karasawa Servo 90 Brake. It's for my E-GO electric bike.

Hi,

This Karasawa drum brake is the only product from Karasawa we're able to get hold of I'm afraid.

Thanks.
Brake Activation
By

I'm new to the drum brakes, and have an older Santana (1989 Visa I think), that has the threading on the rear hub. I presume this will fit, but how do you activate the brake? Do I need a lever and cable kit?
SJS Customer Service:
Hi,

You will need to purchase a brake lever and cable to operate this brake. Drum brakes use the same cable pull as calliper and cantilever brakes so you will need a brake lever suited to one of those.

Thanks.

The existing Arai is giving me trouble. Will this fit the Shimano hub?
Thanks.

SJS Customer Service:
Hi,

This tandem drum brake fits to the same threads as an Arai would so this should fit your hub fine.

Thanks.

Hi,

It screws onto a hub specifically designed to accept a drum brake.

Thanks.
