So I let my friend tryout my new 04 Screw, and once we were clear of the neighborhood I told him to open it up a bit...well, when he tried he then realized that he never disengaged the parking brake and immediately pulled the handle...needless to say I was pretty pissed..my truck is 2 weeks old and has under 600 miles on it. He drove it with the brake on for a couple of miles never getting over 30 miles an hour...my question is, is how bad is it to do this? I didnt smell anything and it rides fine now.

Another question about the parking brake mechanism...what does it engage? The back brake calipers?

Thanks

 

The pedal is connected to a cable that engages the rear brakes only (calipers if you have rear rotors). So depending on now hard the pedal is engaged will determine how bad the friction was on the rotor/drum.

You'll know if there is a problem if you feel any vibration under braking. If not, then I would suspect that the rotors were not warped - and you're okay. Otherwise you likely just used up some pad.

 

The parking brake on disk brake equipped vehicles is a small drum brake setup inside the rotor assemblies on the rear wheels.

If the park brake still holds, you are fine.

 

There's a tiny drum behind the rear discs. This is what the parking brake engages, Not the rear calipers.

 

Wow. Why didn't I know that? I replaced the rear pads on my 1995 T-Bird, but don't remember a mini-drum. Is this just a truck-thing?

 

there was almost an identical post a day or two ago:

Depends on the application....some use the inner part of the rotor as a little "brake drum" for a set of little shoes for the e-brake.

Others just apply the caliper for the e-brake....here is a picture af a caliper style e-brake....notice the assembly to the right of the hose, thats the cable pull for the e-brake

 

another view...you can easily see the emergency brake cable coming into the caliper.....

 

Thanks for posting these pics. Learned something.
