Hydraulic brakes not working I recently got my first bike with hydraulic brakes.

The brakes made some strange squealing sounds, so I took it apart to see what could have been the problem.

I took out the pads and cleaned them, since they were dirty. I was very curious about the bike, because it had a new braking system, so I decided to press the lever, but a bunch of oil spilled out. I put the bike back together, but now the bike does not stop.

Help?

I don't live near many bike repairers, and I really want to bike next week.
They need to be bled. Nothing else for it. To do it yourself, you need a bleed kit and new fluid for whatever brake system you have, along with some other miscellaneous tools. It's considered a relatively advanced job as bikes go.

If by "very squeaky" you mean the loud howl of an oil-contaminated brake pad, you should just get new pads, and degrease the rotor thoroughly with something that doesn't leave residue.
