Ford Brakes

Ok so since ive gotten my stickshift, i have been pulling my parking break a little early when as im comming to a stop when parking. Can this mess a car up? Because after pulling a little hard one time i think i fucked up my brakes. Next time i tried hitting the brakes they didnt start making my car brake until i pushed the pedal the whole way down. It used to start braking as soon as my foot touched the pedal.

Im a pizza delivery guy so i pull the ebrake a lot.

also the light for the ebrake is now stuck on.

the car still brakes at the same speed that it used to but i have to push the pedal in all the way, and its sort of un nerving when your in traffic and have to break and you push the pedal down far enough that it should stop the car, but nothing happens.

How much might this cost to fix? Or do i even need to fix it

You probably ran 1 side of the master cylinder low of fluid.

I would also pull the wheels off and do a brake check. From what I've seen when the master cylinder has a low side it usually means that one set of brakes is just about worn out

What year and model is your vehicle? On some ABS equipped models if you pull the emergency brake and depress the brake pedal at the same time while you are moving you will mess up the ABS system. There is a metering valve that controls how much brake pressure is sent to each wheel cylinder or caliper which is controlled electronically and since you are using the cable to operate the rear brakes instead of the ABS system too little pressure could be being sent to the rear. If you have checked for leaks, sufficient fluid levels and the shoes and/or pads look ok and are properly adjusted and you still have the same pedal, try this. With the engine running and the car chocked on a level surface open all four bleeder screws and have someone push the brake pedal to the floor and hold it there while you close them. DO NOT release the pedal until all screws are closed. Check your fluid levels and road test the vehicle. You may have to do this more than once to get it back 100%. The other option is to have the brakes adjusted at a brake shop or dealer who has the correct electronic device to adjust the metering valve.
