Default How to test parking brake - 08-26-2004 , 09:31 PM






Hello,

I just changed the parking brake shoe on 2001 Youkon Denali for an
effort to pass inspection Adjusted the starwheel and testion at the
brake equalizer. Now I can push the vehicle in neutral but I can not push
in neutal with parking brake applied. The car still moves when running
in drive or reverse gears with parking brake applied.

My question is what is the test. With parking brake applied, you can not
push vehicle in neutral or car must not move when running in drive or
reverse gears. Inspection guy wants to make sure car can not be
moving in drive or reverse gears.

Also the parking brake pedal goes to floor with little foot pressure. Is
this normal. When parking brake applied, I have checked cable tension
and cables are very tight and parking brake lever behind both wheel
moves to the fully open position.

Thanks

The parking brake (AKA emergency brake) should hold the running
vehicle upon application or slow a moving vehicle (usually in the
range of 5-6 "clicks").

I don't know about the 2001 Yukon Denali's but many vehicles have
adjustments inside the brake housing for the shoes to ensure there is
minimal cable travel for application or release. Check that you
adjusted that correctly before you adjusted your cable length.

First thing, you cannot make an adjustment at the brake equalizer (
ie: the cable itself). This was not intended to be an adjustment on
these vehicles....it should simply be tightened all the way up. The
adjustment is made at the park brake shoes and you pretty much
have to remove the rear rotors to do the adjustment. If you have
those park brake shoes adjusted properly, the park brake should
hold the vehicle from moving in reverse or drive. The brake pedal
will feel like mush...this is normal.

Yes, it is normal. I think that you don't have the park brake shoes
adjusted up enough.
