following on from an earlier thread about using these lines, i have some to fit to my 7r.

basically do u take off the old ones, couple up the new ones, pull the fluid thru...

then, where im getting lost, do u bleed each side individually or at same time? cuz u obviously cant clamp braided lines as u can rubber

Yep, just whip the old ones off, replace with new, but you have have to bleed each caliper seperatley.

is it relatively straight forward to do?

whip the old ones off, and stick the braided ones on. Bleed each side separately.
Just one thing - if you have a splitter, you're best off replacing the three line set up with a twin line set up and a double banjo going into the master cylinder. It's cheaper and a better set up

yeah, it a straight thru 2 line set up, no splitter

yeah, pretty much as you described.

Drain old fluid
take off old lines
put on new lines
fill reservoir then bleed brakes

How are you going to bleed the brakes? Personally i reccomend a vaccum pump to pull the fluid through, all you do then is keep the reservoir topped up as it sucks the fluid through until it come through with no bubbles. Then do the same with the other caliper, again keeping an eye on the fluid level in the reservoir.

+ what Caz said

just out of interest, why is it better? I've wondered why before but never come up with any obvious explanation.

I've got braided hoses with a splitter on mine, but they were a 'bonus' when I bought a complete replacement front brake system, I didn't buy them seperately.

how can you bleed each line seperately if you can't clamp them one at a time>?

first time me n baz bled my brakes we used some rubber pipe, and fluid in a milk bottle.

but have had a plan to use a piece of rubber pipe, attaching to bleed nipple with a simple one way valve attached like u get on fish tank air pumps, that should work?

or a syringe?

Syringe is probably best, but fluid in any container and submerse the rubber hose is not different really. You can use anything - aslong as you don't allow air to get back into the system, jobs a gudden.

in that case a one way fish tank valve will work.

Yep, they try to sell the same kind of thing off in Halfords for £15. 2 bits of rubber tube and a one way vavle, it must have some kind of superiority ofcourse.

I can only assume that its due to less restrictions thanks to omitting the splitter therefore reduced losses.

As long as you have the bleed nipple on the caliper on the other line closed then you are not sucking additional air into the system.

That's effectively what the 'one person bleeding kits' you can get from Halfrauds for ca £5 are.

just make sure you leave plenty of time to bleed them, can be an absolute pig of a job to do! which reminds me, really miust get braided lines for mine.

so how much are these new-fangled vacuum pumps?
