This may be a stupid question but i am having trouble bleeding my brakes to install new pads on new rotors. Nothing comes out of the bleeder screw. Do i loosen the banjo on the brake line?

 

You dont need to bleed the brakes just to replace pads and rotors...

 

Yes you do, well pumping actually but, whenever u put new breaks y have to clamp the compressor deal down in order to get them back on,
But after u replace it just take the cap of ur fluid container and slowly pump the breaks continually. Once u do this put the top back on and drive around the block easing onto the breaks alot. And there you have it.

 

Compressing the caliper has nothing to do with bleeding. If you have to crack a bleeder to get the pistons to move then you have a bad brake line.

No fluid should ever need to be removed to replace pads and rotors. You should never top off your master cylinder, because you should never lose fluid unless you have a leak. If you master cylinder is low then you either has a leak or your brakes are worn.

No need to ever bleed the brakes when just changing the pads and rotors.

Now if the OP opened the bleeder valve without pressing the brake pedal he will have to bleed the brakes because he let air into the system. (which I'm guessing cause he said he opened it and nothing came out)

 

Yeah i really screwed the pooch on that one. I knew better but i thought it would work. I got a c clamp to try and push the pistons back. My new pads are alot thicker than my old so i have to compress the pistons so they will fit over the new rotor. Thats what i was opening the bleeder for.

 

I agree with the others...you do not have to bleed brakes to changes pads and/or rotors.

Have you bled brakes before?

 

Yes i have bleed brakes before. I got the fronts done. I went and got a c clamp and it worked like a charm. But it did make my reservoir over flow when i did the other side. Is that normal?

 

Using a C Clamp isn't bleeding the brakes, you're just compressing the piston into the caliper. If these are original calipers, a C clamp isn't a very good tool for the job, as the pistons are ceramic and have a tendency to crack.

If your reservoir has been topped off while the pads are severely worn, you will probably spill a little hydraulic fluid, not a big deal.

To avoid that, do one side, pump up the brakes, then move to the other side. Or take a turkey baster and suck a little fluid out of the res.

As a previous poster said, if you've opened the bleeder with no pressure on the pedal, be sure to bleed the brakes after completing your brake job, otherwise there is a very good possibility you've introduced air into the system.

 

I know using a c clamp is not bleeding the brakes. I guess i should have started a new paragraph.

I drove my truck after i finished and the brakes were a bit mushy. Im going to take it tommorow to have the rear rotors put on and the brakes bleed so i dont have to rely on the ol lady to keep the pedal pushed haha
