Question Brake problems

sorry guys, im a newbie when it comes to changing brakes, i took the the calipers off all the way, painted then while i was at it, bled them through the bleeder screw, and drained the resevoir for the brake fluid, remounted evertthing added fluid to the resevoir and now when i push the brakes it goes down to far without resistance and seems like the power brakes are gone, the car still stops but needs alot more force to do so, anyone know whats wrong??
thanks in advanced

As long as you buttoned up everything right then you still need to do some bleeding. Go around to each caliper and re-bleed. You have air in there somwhere

unless you have aspeed bleeder system you will need two people to do it correctly.

Start with one bleeder and do the same process for each one.

Have someone sit in the car and pump up the brakes. Open the bleeder and see what happens. Do this a few times to make sure. If you have a steady stream then close it and move to the next one. If you get spitting or air etc. then just tighten, pump, bleed, tighten pump bleed until it is steady. Then when all four are done top off the master and you are good to go. By this time it should feel rock hard to depress the pedal.

Good luck

I just bled mine a few days ago for the first time. I used the two man method. You do not need to start the car or even have the ignition on. It is better not to in-order to avoid any possible problems with the ABS system. I got a little brake bleeding kit from Auto Zone that includes a little catch bottle with a magnetic mount and some clear tubing.

Method I used:
Person in the car pumps the brakes a few times to build up pressure then holds the pedal down. Person at the brake then opens bleeder valve just a little until fluid comes out. As the fluid escapes the person in the car should notice the pedal will move towards the floor. When the pedal gets to the floor the in car person should indicate this to the person at the brake. The brake person must then close the bleeder valve before the fluid stops. The brake operator must not let go of the pedal until the bleeder valve is shut or air will be sucked back into the caliper via the bleeder valve. Once the bleeder valve is closed the guy inside can let up on the brake pedal. Repeat this a few times. When you open the bleeder valve and no air escapes, seen as bubbles in the clear tube, then you are good. Repeat a few more times to be sure. Best order for bleeding is passenger side back, driver’s side back, passenger side front and finally driver side front.

Hope this helps,

Oh also periodically check the fluid level in the resivour. At no point in time let it run dry or you will have to start all over.
