Hey Guys

I just have got back into biking and i have never worked on hydrolic brakes and thought i would give it a go at bleeding my brakes as seemeed easy from what i have heard

i have hayes nine's and i thought i was undoing the bleed screw but found out after it was just a screw for reservoir (see pic i have marked in red)



i pumped up the fluid from caliper with a syringe and air come out the screw then fluid so i tightened the caliper up then put screw back in and tighten up expecting the brake lever to be solid it was squishy and bubbled where i took the screw out so i tightened it more and then ping the screw snapped...ooops

have i messed up the lever for good

i understand now i should of taken out middle gromit as thats the bleed stoper

anyone understand what i have written? or is it drival ...he he

nicklouse

well it all depends on if you can get the remains out.

i think i can if i take of the cover......thing that confuses me is when i tightened all the way it was bubbling when i pulled the leaver like it needed more tightening to seal it up to close the system off thats when i tightened it and it snapped

i dont understand why it didnt seal the system like it was before i started

i only bleed it because it was a bit spungy ,,,wish i hasnt done it now ;0(

it's spelt 'hydraulic'.

and 'lever'.

Argh!

Take it to a bike shop, and stop off at the library on your way home.

Yeah cheers

I was looking for help not an english lesson

At the end of the day i was up for learning how to take my bike apart and rebuilding it
I can afford to service my bike but i want to be very hands on and learn it all myself

Thanks for nothing

My hayes nine felt 'spongy' but after reading comments on this forum I just gave them time to bed in.

It took about an hour or so just riding and applying the brakes and now they have a more sharper bite.

Not really useful but thought I would give my 2 pennies worth

CRC will sell you the required replacement parts.

You will need

1 x http://www.chainreactioncycles.com/Mode ... elID=20109
(should come with the Olive you need)

plus

1 x http://www.chainreactioncycles.com/Mode ... delID=7478

unless you follow the instructions to cut the hose and use a ring spanner to remove the Olive nut. If you don't then you will need a stud remover as well. Of course cutting the hose might mean you need a new hose.

Or if you can get the remains of the screw out then only

I'd give it to your LBS to sort out or just get a new brake, H9's are cheap but there are others just as cheap which offer better modulation.

Just for the record (you may well know this now), the bleed nipple is down on the caliper.
And it's a proper bugger :evil:

And there's lots of sets of instructions to download on the Hayes website (though they're still fiddly it's a lot less fiddly when you know what each bit is ).

You missed a couple of capital letters. :roll:
