I have a 1965 ford mustang, put new bakes, adjusted the shoe brakes, fluid level is ok but the pedal is too low. what do you think t may be the problem ?

Have rear drum brakes? may need adjusted up tighter...........check fluid level in reservoir...........
Look for any wetness inside the wheels where a leak may have started.,or look for seeping brake lines.don-ohio

Is it drum brakes in the rear and is that where the noise is coming from? If so, the baking plate behind the shoes may need lubed and be adjusted properly.

If the shoes are adjusted to where the drum drags on the shoes while turning the drum,then the master cylinder is the most likely cause,some times the master will by-pass and cause this,and ,or will leak fluid out the rear of the master into the booster.

Hi!!

Check your brake fluid level and the condition of your brake pads/shoes.

The ABS and/or Brake Light some times come on when the fluid level is low.

If you still want to check the switch, it is located on the upper part of the brake pedal

Check your brake fluid level. if ok, have the system bled as there may be air in the brake system. If your fluid is low, have the brake system checked for leaks. Hopefully this helps!!

make sure the rear shoes are manually adjusted up properly ,then is still no good renew the master cylinder because the seal between the front and rear chambers could have gone ,but i do feel that you should manually adjust the rear brakes up properly,slacken handbrake cable before you do this though

Have you checked your brake fluid? As your brake shoes start to wear it requires more and more oil to push the brake shoe to the disc or drum so during the life of your brakes you should check the brake fluid level periodically. I think there is a low brake fluid level sensor that warns you if you're getting low. It's also a sign your brakes could be nearing the end of their life. If you run them till they're metal to metal it will significantly increase your repair bill as you'll have to have new rotors or drums or have them turned.

Bleeding (to fix soft-pedal) the brakes only takes the trapped air out of the system. Excessive pedal movement is fixed by adjusting the brake shoes (drum type brakes) out further. Many vehicles will self-adjust the shoes by stepping repeatedly on the pedal while moving in reverse. Disk brakes self-adjust after the first application of the brakes (be sure to recheck fluid level in the master cylinder). Hope that helps.

the motor just pumps hydraulic fluid into the lift pistons. If you are low on fluid, the motor can't create enough pressure to run the pistons. Check the fluid level.

ADJUSTMENTS Fluid Level

1. Remove rear seat. Refer to Section 01-10 .

1. Carefully remove the rubber fill plug from the back and the reservoir and check the fluid level. The level should be at the bottom of the filler hole. If necessary, add Synthetic Mercon® Multi-Purpose Automatic transmission fluid E6AZ-19582-B or equivalent meeting Ford specification ESR-M2C163-A2. CAUTION: Do not overfill or the reservoir seal could be blown out.
   

1. Replace fill plug with a new fill plug.

1. Bleed system as outlined if necessary.

Sounds like air in the fluid or low fluid level. Check the brake fluid level under the hood and make sure it's adequate. If not, top it off. If it is, have the brakes bled and the fluid topped off again, and you should be OK, as long as nothing was damaged during the recent brake job.
