Brake pedal low

Also the parking brake does not engage. Since this is a rear disc and the parking brake is inside the rotor I didn't know if there was a special procedure to adjust the parking brake. And if I adjust the PB wil that bring up brake pedal
Thanks

normally a low pedal is air in fluid or very worn brake pads....this is because the caliper pistons are almost in the full out position...

also extermely worn brake rotors....

I don't know how your parking brakes are designed...

Adjustment is somewhat easy. On the inside drum plate is an oblong-shaped rubber plug. Removing the plug will gain access to the brake shoe adjustment wheel. It has small, serrated teeth around that allow it to spin one way only. Jack up the rear and support with jackstands. Removing the tire first makes access easier and makes adjustment easier to feel and hear. Then use a flat-blade screwdriver to turn the adjustment wheel, counting the number of clicks. Adjust only a few clicks at a time, then try to rotate the drum. It should rotate freely with only the slight intermittent feeling and sound of the shoes dragging against the drum. Once you get there, the total number of clicks needed should be close to what the opposite side should need, but err on the low side. Repeat for the other side and check your park brake travel...it should be less than before.

There should also be an adjustment screw or turnbuckle to adjust the length of the park brake cable (the cable runs along the frame on the driver's side, and the adjuster is usually located under the cab) as it will stretch over time, but I highly recommend adjusting the rear brakes first. Hope this helps!

Thanks guys,
I had already bleed the brakes just to get fresh fluid in the system. Didn't help the pedal but I always like to do that to keep the moisture content out. jd mc thanks, I'll do that Monday as the guy works with me. I've heard from others that the pedal is somewhat low (normal) compared to others. But this should get the parking brake working.
Thanks again

With engine off and after pumping vacuum down.
Does it have a full pedal?

Does it stop good when brake pedal is applied?
Any ABS or brake lights on?

On bleeding brake if air has got into the ABS system it requires a ABS brake capable scanner to bleed.
