I've just cleaned the rear brake on my bike

[LondonRider]

Hello I have just taken the bike apart and cleaned the rear brake on my honda cbf 125 following on from this thread:

https://www.themotorbikeforum.co.uk/viewtopic.php?f=5&t=63578

I have a few questions.

1) There were some rubber blocks, pic below. One of the blocks was broken;

a) what are these called? I need to buy new ones but have done some basic searches and can't seem to find them.

b) It's not dangerous that it's broken right? Cause I've assembled everything back together and the broken one is currently in use as I was not anticipating needing new ones.

 

 

 

2) When I cleaned the brake I noticed only one of the springs and side of the brake shoe was working. Pic below (when pulled only top side has expanded as you can see). Is this correct? Is only one side supposed to be working or are both supposed to press outwards?

 

 

Thanks!

The rubber blocks are called cush rubbers.The thin bit of rubber linking 2 together can break,one is gone in the back of my RGV and its not really an issue to use like that.Once they are fitted inside the hub,they cant go anywhere.

The brake spring is ok as well.There is only one cam which turns and opens the shoes,so one spring does most of the work,

Unless one of the springs is not holding the two halves of shoe together then they are both working! They keep the shoe away from the drum unless separated by the camshaft, which as says Bianco2564 says only happens at one end.

I do not know about Honda, but Yamaha's parts catalogue call those rubber things "dampers". Although unless changing the sprocket you did not need to take those out. Once you have loosened the wheel just just roll it forwards to create enough slack to take the chain off the sprocket, and then the reverse when putting it all back together. It is easier just leaving all those bits and bobs in the wheel.

I guess brake3.jpg and brake4.jpg must have been too exciting for us.
