Rear Brake line Re-route

Summer holidays are here, so time to crack on and get this rr on the road! Got a job for the summer so plus side i can start throwing money at the bike, downside i'll have less time to spend doin her up.

So from delinking the brakes, i now need to re set up the rear brake. Im using the original rear caliper so some brake line managment needs attension. The rear caliper is a 3 piston design, with the outer 2 pistons in one hydraulic circuit and the center piston on its own. The trick now will be getting all the pistons to work together now ive taken the two brake line feeds away. To save weight and to give a cleaner look ive opted to mount a single line from the master cylinder to the caliper and then adding a short bridge to tie the 2 hydraulic ports together. The rearmost port then will be a double banjo bolt, one hose goes to the master cylinder, and the other is the bridge line that goes to the center piston port.

- here's a look of how the rear brake lines originally look. The chainguard hides the beauty of the single sided swingarm and it hides the chain. The only purpose its good for is holding the two brake lines inplace, but as i want to get rid of these, the chainguard definately needs to. Also its a weighty bit of plastic, so by getting rid, its another weight saving mod.

Chaingaurd removed and having a closer inspection of the swingarm ive have a great idea for the rear brake line route.

Routing the line from the rear master cylinder, into and through the swing arm and out sumwhere near the rear caliper, giving the cleanest look as no brake line will be visable along the swing arm :)












- new rear master cylinder and valve, taken from a cbr600F to achieve a good braking balance.

- So on the top of the swing arm, near to where the shock sits theres an approx 10mm hole left from where the chainguard plugs into.... perfect for a brake line to go into?

- Underneath the swingarm near to where the brake caliper sits theres another hole (approx 12mm) this could be too perfect for the brake line to feed through.... using some wire and feeding it through the swingarm, happy face it all feeds through and this could be possible.

- Ok, so puchased some universal brakelines, banjos, and washer.... time to rig it all together. Firstly i need to connect the outer hydraulic pistons together.

- Pistons connected :) (the unversal kit i bought was really good (venhill brake lines), braided steel, cut well and cleanly with a hack saw, and part connected up nicely)
- I fed the wire which i used to locate through the swing arm, onto the brake line and pulled it throuh...15mins of maneuvering it, making sure there were no kinks in the line and the line is now inside the swing arm :)

- Heres where the line comes out on the underside of the swing arm, i added some rubber bungs on the exits to avoid rubbing between the swingarm and brake lines.
- Here how the rear caliper looks, with the braided brake line set up complete

- A top view of how the brake line re-route looks (minimal lines visable)

- Chain back on, overall look of the rear brake line re-route complete :) i think it looks awesome! it makes the swingarm look so much cleaner, and makes the gold chain much more of a visually pleasing feature in comparison to all the original set up.

    1. Glad u like the blog josh and its awesome its inspired you to do your own project. you'll have to keep me updated with how you get on, and id love to see pictures of any completed work. message me any time if u need info on how ive done anything so far. Custom paint job will be really nice and i like the idea on the sheetmetal. I was originally going to paint my swingarm black too, but am going to keep it original for the time being as im not completely sure on the colour scheme im going to go for, im thinking black for the fairings, with either silver and gold details (gold wheels) or silver and red details....
