Brake lines change
on: 19 Dec 20, 01:01:56
Afternoon all......
I'm about to swap the brake lines out on my 2015 SX

But just before I start, a 'mate'  :023: has suggested that changing the brake lines may upset the ABS pump and it will need to go to the dealers to be reset (££££££)

Before I crack open the spanners, can anyone confirm if this is true?  :027: :027:

Cheers.

Not true..  It will be fine.

Changing the brake lines won't do anything to upset the abs.

If you haven't already get a 1 man brake bleed kit (sportsbike shop sell Oxford ones for about £10) best money I ever spent for bleeding brakes, it's simple, cheap ant let me flush old for new fluid on all 3 lines in 10 minutes, if I wasn't being careful I think I could have done it in 5 minutes.

Front's are done - easy......
Rear - looks like I need to break out the Abba stand and get the rear shock out........... job for tomorrow

I've got a vacuum bleeder - have to agree - best money spent!!!

I found that I could get to the brake line connector block mounted to the frame and get to the bolt that holds that in place by use of a long extension bar from the left hand side of the bike.  So the shock didn't have to come out.   But actually I suspect if you can get the bike on the Abba stand then taking the shock out may not be that difficult either.

I a;ways found it hard to start bleeding when the system has been drained. But I have found a great way around it. Before you drain the system remove the calipers and pump the brakes to get the pistons out. Keep at least 1 brake pad in to ensure the pistons don't come all the way out. When you have attached the new lines, press the pistons back in again. This will push the old fluid through the lines and into the reservoir. You can then bleed the brakes as usual.

Yeah - the fronts were done........
But some numpty left one of the caliper banjo bolts loose overnight and found all his brake fluid over the garage floor this morning......

And now I can't get any feel to the front brake lever.
I've tried vacuum bleeding, reverse bleeding with a big syringe but still no feel in the lever.
Am now leaving it with the front lever tied back in the hope that any air will work its way back to the reservoir.....

Any other suggestions?

Like l said. Push the pistons back in so that it will push all the fluid from behind them up to the reservoir. You should then have pressure to bleed them.
