Damned internal routing. Best way to replace a rear brake hose?

[ishaw]

Fettling my son's bike today as it will get some use over the coming half term week.

Noticed the front brake had no pressure, so thought I'd bleed it but previous owner has rounded the bleed bolt on the lever. No problem, I was going to swap in some xt brakes anyway so that solves that brake.

However, the rear brake is internally routed and I didn't have the time to faff with that today so he's got odd brakes.

In preparation for when I get time to do the rear, What's the best way to do this.

I suspect from the front down as the hole to route it through is much smaller than by the BB.

I plan to tape the new hose to the old and pull through.

Would this be the right way to do it or am I best going from the bottom up?

Or is there a better way entirely?

I usually do it with a short length of spoke, generally about 50mm of the centre section of a butted one.

Stick that in the end of the hose currently in the frame, then the other end in the new hose.

Try to push the old hose out with the new hose to avoid the old and new hose separating, you may have to gently pull the old hose whilst pushing the new hose through.

I don’t really worry about which direction I go from.

I’ve had to do this far too many times, this method has had good results for me.

Good luck!
