Hydraulic Disc Brakes (setup/fixing, stroker trail)

Hey Guys,

I recently bought a Gary Fisher HiFi Deluxe 29er.

Till today, I had been riding it around town, and places I can ride too from home. I had not had to transport it anywhere, or take the front wheel off.

So today the bike had its maiden ride, drove to some trails ~20 miles from home. I transported it with the front wheel off. Bike rode fine. Took the wheel off and drove it bike home.

So I get home, put the wheel on, and ride around to the back. I realize my front brakes aren't working! I take the wheel back off, and inspect the calipers. The piece that moves when the brake lever is depressed is sort of sticking out. I pull the brake levers in some, and I see this pad moving forward, and then brake fluid dripping out from behind it (out of the caliper body).

Is this normal? Can you not depress the brake handle with the wheel off? How could you transfer the bike otherwise? What was my error here? I guess I need to buy a brake bleed kit to fix it now.

thanks guys,
Corey

no this is not normal. from the sounds of it the piston (the part that moves the pad) has come out of the caliper body. no you can not depress the brake handle with the wheel off. you can still transport the bike with the front wheel off, just take care not to press the brake lever. or get a shim to place in between the brake pads that keep them from moving during transport.

Thanks. So I need to just push the piston back in there, and then get a bleed kit?

Hopefully. If no dirt got in the system when it was open. And Lofsnjoke is right, it's an absolute no-no to operate the brakes without a rotor or block between the pads.... as you've now found out.

I don't believe any dirt got in the system.

Out of curiosity though, what would you have to do if some did?

And thanks guys, you've really been helpful.

thanks,
Corey
