[Closed] Brake hose replacement advice

Why are you replacing the hose?

Epic bleed kit is good. Removing fluid you can just fit the syringe to the caliper, open up the lever end and suck, that'll get most of it. And then to refill, just follow the bleed instructions.

Is it not easier to get the system air free if you avoid draining it completely?

Not really if you're replacing the hose- avid bleed process will make the rest simple enough. But yes normally you don't want to make it any harder than it has to be. Personally I wouldn't drain it but then I have an unhealthily blase attitude to corrosive poison 😉

Oh, and sorry for the slight hijack but I just happen to be in a possible hose replacing situation as well.

Replacing as it seemed easier to do that and feed the hose through the swing arm whilst empty.

TBH Mosey, if the hoses are suitable length I wouldn't replace 'em, just take an end off. YMMV though but that's what I did with my Formulas.

Would you say the same thing goes for Shimano brakes?

I don't know the latest Shimanos tbh. My old M775s were dead simple once you threw away the instructions 😉

Yeah think ill just remove an end. Lever or calliper? I reckon calliper as it must be easier to feed through the swing arm grommet end first?

Unless you have a crimped-on fitting, caliper end every time. Don't forget to feed the hose under the shock before you start,and try to get an outward curve in the first inch or two as the hole inside the arm is slightly offset. Once pushed in, push it until it just passes the exit, hook it with a bent piece of wire and pull it snug against the arm, pull it back through until it's end is exposed, where it's then an easy job to push in another bent piece of wire(pointed goes in easier)to guide it out whilst pushing the hose from the front.(try to avoid removing the grommet, they're a **** to refit once there's a hose in them).

Brilliant thanks, ill order an epic bleed lot and get it done this week.

A little tip for replacing the hose or a gear cable through the swingarm:

Put an old gear cable inside the first inch or so of the brake hose before removing and tape in place.
Pull hose out slowly so that the gear cable is pulled through in it's place.
When completely out (the hose!), do the same to the hose to go back in, remembering to put any grommets on before threading (assuming you're threading from the front).
Pull gear cable through slowly, wiggling the hose to get through the internal baffles.
When hose appears out the far end, remove gear cable.

Saves one hell of a lot of faffing!!

When you say inside do you mean inside or taped to the outside?

If I'm not emptying the hose how can I put a gear cable inside?

I'm going to give the gear cable a go now.

Push it up the inside a bit, less likely to snag on anything on the way through.

If you're taking the caliper or lever off, you'll most likely need to bleed anyway.

I think I'll do calliper and feed through from the front. Bleed kit is ordered so that's happening this week.

Can I just unattached the hose at the calliper and thread it through?

Won't it gush fluid?

Take the lever off the bar, if it hangs below the swingarm level it's not going to have gravity helping the fluid run out(not that much will come out anyway).

Right cheers, gear cable is done and through. Must have been luck but the gear cable popped straight out the rear hole.

Brake cable attempt later tonight. Now it's rib and beer time.

Thanks everyone. I really appreciate the help.

Here it is so far, KS Lev to be fitted. I'm proper happy with it. Can't wait to ride it now.
