Ok so I'm thinking about putting hydraulic Disc Brakes on my Prophet. Replacing my Avid BB7's with a set of Hayes HFX 9 XC hydraulic disc brakes.

Anyway, I have 6" rotors and replacing with the same. 6 bolt pattern. Are there any issues I need to be aware of? Do I simply remove my existing brakes, cables, rotors and levers and swap them out? Can I leave the rotors so I don't have to mess with them? I know cable length may be an issue but what I am mainly concerned about is my lefty hub? Does it matter?

Also is there a LBS near Afton that is open on Sunday afternoon who might want to assist in this matter?

Any wrenchers please post up. I could use the advice.

Thanks a bunch.

Dan

ther shouldn't be a problem if its the standard 6" rotor, but id still swap it over just to make sure, but see if your roters you have now work.

its just the easy take off the grips and unbolt and rebolt as long as you don't have to fill and bleed them urself.

that reminds me... anything inpaticular i need for deor hydrolics disk brake oil? my rears gettin low and mushy, found a leak in my line and replaced it a week ago and its gone really soft since i last filled it, andy advice would help.

Dan,
You'll be fine using the same 160mm rotors.
a 160mm rotor=a 160mm rotor. If somebody believes different please inform us before I'm held responsible for breaking his calipers!:hit:

The only thing I'd be looking for are two things:

1) Pad wear from caliper to caliper...you may want to remove the pads and push the pistons all the way out before mounting;
2) Some rotors actually have different thicknesses depending on mfr. Step 1 helps address this.

Your good to go as long as your not thinking about cutting any cables which would require a bleed afterwords.

If you ever do need to bled you hydros one thing I have learned is to remove your pads and rotors, or use a junk set, set a block in between the pistons. Open it up and start bleeding when your positive that all the air pockets are out close the valves and clean everything to ensure that no brake fluid is on anything then reinsert pads. Know this sounds as if it is a PINA but it will actually save you time in the long run.
