Speed bleeders...

[PosterFZ6]

Hey guys,

Do you know how many speed bleeders we need for the S2 version.

The official speed bleeders website doesn't list any for the S2 generation.

I would think that you would only need 3, one for each caliper..

Just a guess though...

Do you know the part #s?

S1 version had different front brakes as far as I remember.

I'm sure all the speed bleeders are all the same and all go in the same holes. Should be three. :cheer:

 

[david323]

The S2 front brakes are the same as the R6 brakes, aren't they? Could you just get the part # for the R6? And I don't think the rear changed between S1 and S2...

Bleeder valve thread and seats should be standard on all calipers.

I got one of those Motion Pro speed bleeders that I use to bleed each caliper individually. Keep in mind that your speed bleeders may need to have the system already primed with fluid to work. In other words the master cylinder may not have the force needed if you have air in the system. The air compresses at a different rate than brake fluid and my not pop the valve properly.

In another words I shouldn't drain out the whole system before installing them. correct?

That's what I'm thinking. One of our members emptied the system and had lots of air and had to get fluid in because the auto bleed wouldn't work with lots of air in the lines.

The front bleeders are 8mm by 1.25 or SB8125L

The rear bleeder is 8mm by 1.25 or SB8125L

You are totally correct - I had these on my last bike and got a little air in the system and was SOL. Had to get a Mityvac to flush them out. IMO you're better off buying a vacuum bleeder - costs the same or less and works better. Also some have had issues with sealing and stripping IIRC.

Interesting.

I have not considered it.

Any recommendations?

I have a cheap vacuum bleeder, does the job fine. Can bleed front and rear from scratch in about ten minutes.

i have a pair of goodridge speed bleeders size 8mm x 1.25 laying around ill give them to u for $10 and yes u have to have the lines primed with brake fluid before u put them on

word of caution.. when you thread a speed bleeder in, it does not seat down to the hex..in plain English, when you feel its not turning any more, do not keep turning.. i made that mistake and ruined a perfectly good rear brake caliper.. otherwise, i have nothing but good things to say about the product, but just be careful when installing...

i just use a cheap plastic syringe with a hose to bleed and suck the fluid through...

not sure why you'd want to complicate it so much

Agree! Use a torque wrench!!!

On a cycle, I don't even bother with speed bleeders, since my arms are long enough to both operate the brake lever, and turn the bleeder valve. :thumbup:

I use them on my car, but can't justify them for the motorcycle.

Indeed.

But for a small cost the time saved is priceless. I change brake fluid twice in a season.

Making it a quicker job is worth it for a small cost of the speed bleeder.

it dawns on me...

if you really do change fluid twice in a season, then you must know how ridiculously simple it is to bleed your brakes.. it boggles me then how you feel you need to spend any money on speed bleeders.. I'm not being mean or sarcastic (i do have a chip since they helped me ruin a caliper), but i really do not see the benefit of spending roughly $10-$15 (what about 1/2 a tank of gas) for something that will "help you" twice a year for a whole 10-20 min job..

How did you ruin your caliper? Cross thread?
