Experience with shortening hyd brake lines & bleeding ?
Postby MichaelB » Sun Jan 29, 2012 7:41 pm
Most likely place is here, so thought I'd ask.
Anyone with experience of shortening hydro brake lines and subsequent bleeding ? Any particular tips and/or tricks ?
Pretty mechanical and handy around cars, but bikes are different, so any advice will be appreciated please

* a bleed kit with fittings for your brand of brakes,
* compatible oil: mineral OR DOT, depending on brand. Don't confuse them or you will destroy your seals, and then yourself when they fail unexpectedly.
* a new barb + olive for eahc hose end you need to cut.
* a brake shipping block to put in place instead of the pads so they don't get contaminated by any brake fluid spillages
* brake cleaner spray and a clean shop rag to decontaminate caliper and disc if required.
Once the barb and olive are compressed onto the hose end by installation onto the master cylinder they can't be removed for re-use, which is why you need a new set. If you're on Sydney's northern beaches I can probably assist. Avid Elixirs have a reputation for being difficult, but that will be a learning experience

Is there a std place to get the nipples/barbs/olives etc ?
Is that something that the LBS can help with ?
I can get a bleed kit from Wiggle.
Will think and research a bit more and then post some more Q's.

Nah.. been procastinating about bleeding mine. Mate gave me a hand to do it about 18 months ago. Original pads were still OK at time of checking then. Need to bite the bullet and be a big boy and do it this time for myself. Time for me to brush up on Zinn and go for it...
Hit me up via the BNA dm; I'll get an alert. If y'know, you know.

My LBS doesn't stock them / doesn't sell them separately, so bought the last lot for my Shimanos from c r c. Before that I got some from Clarence St Cyclery's workshop.MichaelB wrote:Thanks for the other advice, but re the parts required, need to source them from where ?MichaelB wrote:

Here is a pic of the caliper and brake line if that helps. Is it the same as the hope ones ?
Damn, that was hard to do fro. This so called smart phone !!!!
Edit : From one of the links, it shows a banjo style fitting as having these internal bits
or is it something else ? The tes=xt in the Bike radar & Bike rumour sites mention that the Shimano bleed kit is similar (better than Avid's), but on the TRP site, there is no listing for the spare parts needed to shorten the lines.
Help ....

You can't then get 'em off to be able to re-use them when you shorten the hose.

At least I have a picture now of what I need, so I'm miles ahead there.
Many thanks guys. Time to place an order tomorrow me thinks and take advantage of the Wiggle TDU20 code to save another few bucks

Not really, just want to tinker and see if the Hydro hype is true or not, so whether I need to hold out buying the Volagi until Hydro STI's come out.Crittski wrote:Wow Michael, cutting edge!

Hi Michael,
I’m not sure which fittings are compatible with the TRP parabox. When ours arrived it included fittings to shorten the lines. I would assume that yours will include these as well.

Ended up ordering it from Merlin Cycles in the UK, who had one in stock (somehow, as others were expecting it in mid-March), and received confirmation that it is in the post
Thanks for all the help and advice offered, and I'm sure I'll revive this thread as the time comes to do the "operation" !!!!

Having a think about it, is it (the bit highlighted) not possibel at all, or just too damn hard to make sure the parts are OK ?trailgumby wrote:Of the four brass bits in the row closest to camera in the top photo, you need 1 each of the two on the left for each hose you're going to trim. The thin edges of the brass collar (called the "olive") at far left get crimped down into the hose by the force of tightening the threaded collar into the master cylinder or banjo (depending on the brand), and this stops the next fitting, called "the barb" from coming out of teh end of the hose.
You can't then get 'em off to be able to re-use them when you shorten the hose.
What is the hose made from ?
