Can I swap sram hydro brake hoses over?

Posted on
  • Bought a bike with sram rival hydro road brakes that are set up the wrong way to my preference. To avoid sudden death on my first ride I want to swap the brakes over. Is it as easy as just unbolting and swapping the hoses over, or do I need to replace olives / o-rings or anything else?

  • I've swapped them doing the same job at the lever end without the need for new parts but you'll need to refill the system.

  • That what I like to hear - thank you. Anyone care to say the opposite before I start?

  • You won't die if you don't fit a new olive but it might be better if you do.

    You don't need to refill if you are mindful of gravity and the behaviours of fluids and air.

  • SRAM road levers can be a right pain in the arse, had to do mine 3 times last time, and I followed the instructions to the letter.

  • Never done hydros before. If i swap the olive so I need to swap o-rings as well?

  • Not sure about o-rings in the connection. If SRAM are like every other hydraulic brake, the seal is provided by crush fit on the olive.

    Never done hydros before.

    Save yourself a headache and get a pro shop to do it? it's not rocket science but fuck me, it's a great way of trashing an evening.

  • Found this video on how to replace the hose . Isn’t this the same procedure minus the hose cutting? Seems pretty straight forward if so?

  • Fucking hell SRAM, why is there a banjo bolt at the top?!

    Ugh what a ballache. Spinout is probably right, looks like you have to bleed the brake unless you can get the hose out and swapped without pouring all the fluid from the reservoir over the floor.

  • Heh. Yeah, that was always fun. It can be done without a rebleed, but you have to be really anal about it. Once the reservoir cap comes off with 4 torx bolts, the banjo can be undone, and then you can't lose any fluid.
    Easiest is just to drain the whole system and start from scratch after the swap. Typical SRAM.

  • I'd thought about changing my hoses to Kevlar braided ones... Don't think I'll bother.

  • There's very little point. It's one of those things that's constantly argued about in the automotive world as well. If you're out and out performance, yes. Otherwise, no.

  • Am i? Hmmm

  • Not watched the video but SRAMs own service manuals are pretty decent.

    A few tips..
    Do use a torque wrench, especially on the banjo bolt. Do follow the sequence when refitting the resovoir cover - I didn't and it slowly leaked until redone.

  • Thanks! had a look through and the levers aren't Rival, but looks very similar? Looking through the manual my understanding is that I can just swap them over but should prob replace o-rings?

    Apex? Pull back the hood cover, if there is a 4 bolt resovoir cover.. good chance it's all the same inners. I didn't replace the o-rings, on both occasions I've done this, they were new levers.

  • Mine are Rival

    Totally misread that, it's exactly the same inside...

  • aces, aces everywhere

    thanks for the input, really appreciate it!
