Braided lines worth it ?

I can't speak for BTR, but I own a set of Hel braided lines for the front and rear and I love them.

I have goodridge braided hoses on mine front and back and there brill never had a problem and the braking is massively improved and it was only £40 for both and you can have them any colour aswell

I can't seem to get all the air out of the system any clues ? I have flushed about 200 ml through front and rear and still getting air out.

Probably a silly question but are you putting a bit of pipe of the bleed screw into a half full jar or brake fluid when bleeding it??

I had this problem with one of my previous bike (fzr 400) and it turned out a seal in the actual master cylinder was gone and that was stopping it from bleeding properly

The GS brakes(particularly the front) can be a little tricky,but flushing 200ml and still having air bubbles is too much.This may help and if it doesn't then u have a different problem.

Nathcarr do you have a ebay link for those lines? Also was there any modification needed for them to fit or was it easy?

I haven't jimbob and its my apologies because after going to see the bike today to get my calliper, there actually hel braided hoses so that's my bad. I got them from a local dealer that seals all kinds of bike stuff like clothing and accessories and he has accounts with everyone so got them at trade price rather than retail. As for any modifications no none were needed 😊

I've been bleeding my brakes for an hour now and still no pressure doing exactly what the woman in the video is doing any ideas??

I found that if the bleed nipple was not fairly tight ( tighter than I am used to doing them up on other vehicles) it would suck air past the outside of the nipple.  I have borrowed a vacume bleeder to see if that dose a better job.

Are you using the correct procedure to bleed your brakes?

Squeeze the brake
Open the drain nipple
Close the drain nipple
Release the brake
Repeat

Don't let the reservoir get low on fluid.  If you are and the air bubbles won't stop coming then you have air getting in somewhere.  Check that the banjo boots are tight and the crush washers are installed and are fresh.

All sorted had a shaZam! load of air in the braided hose removed the banjo bolt and just pumped the fluid through until the fluid was just coming out connected back up was sorted within 5 mins after that

I missed the start of this thread... if you have the stock rubber lines and your bike is more than 2 years old the lines should be replaced regardless... 2 years is the stated max life for rubber lines and they will start to swell when applying pressure... braided is definitely the way to go unless you want it to remain 100% stock for some reason.

As for not getting a good result from bleeding, there are two ways around this.

1. Get a suitable syringe and flush the system by injecting the brake fluid from the caliper end, meaning any air in the system is pushed up to the master cylinder. Obviously you don't do this with a full master cylinder :D (FWIW I haven't done this method myself). I have done this every time I have flushed my fluid with 100% success.

2. Flush/fill the system as normal, and once you've got most of the air out, use a bungey cord and strap the brake lever tight against the handlebar overnight. You will just about be guaranteed to come back to a nice firm lever in the morning as the pressure will force those remaining pesky bubbles up into the master cylinder.

Good idea,particularly if you've done brake modifications and your not exactly sure what "normal" is.

Yep, very true! My M/C is an aftermarket one with a slightly smaller diameter bore to stock, so between that and the braided line I had no idea what to expect... the answer is slightly more lever travel due to the smaller bore but better feel and pressure for a much better braking experience  :thumb:
