This is a how-to on swapping the OEM rubber front brake lines out for a braided stainless steel one to improve braking performance. I've gone for the single line direct to the caliper from the master cylinder (for racing purposes) but you can also buy two piece braided line kits that retain the ABS unit in the braking system.
1. First you need to remove the fuel tank to provide easy access to the ABS unit. Note the white electrical connector you also need to cable tie out the way.
2. Pump out as much fluid as you can through the caliper bleed nipple then pack a rag around the top banjo fitting to catch any drips before unscrewing the bolt from the master cylinder.
3. Remove this line retaining bracket altogether.
4. The banjo bolts at the ABS unit end are tight. I used a 3/8" drive ratchet plus extension with a wobble attachment into a 12mm socket. Undo and then remove the top line.
5. I used a 1/4" drive rachet to sneak under the frame rail and get the banjo bolt for the bottom line out. Once this bolt is out then remove the other banjo bolt at the caliper end and remove this line completely.
6. Plug the two holes with bolts of a thread 10mm x 1.25mm pitch. This is a 'metric fine' thread not your regular 10mm thread. Fit crush washers made from aluminium or copper under neath the bolt heads. You will see I used a socket head bolt in one of the holes because there wasnt enough room to turn a hex head bolt.
7. Thread the new cable through the steering head ensuring it doesn't foul anything. My cable had a sticker on the banjo fitting that goes to the master cylinder end to stop wrong fitment. Attach using banjo bolt and have one washer on each side of the fitting.
8. Attach at caliper end.
9. Press rubber block into line retainer
10. Fill line with brake fluid using a syringe held firmly into the bleed nipple. This method pushes any air to the top and out the master cylinder. Watch the sight glass in the master cylinder and stop when fluid level meets half way. Lock off the bleed nipple and fit lid to master cylinder.
You may find you need to do some further regular bleeding to get rid of any trapped air in the system but a ride will soon tell you if it feels like it needs it or not.
That's it!
