Hello and welcome to justanswer.com

Richard :

Did you recently have any brake work done to your truck?

Customer :

NO

Customer :

I just applied electronic emergency brake switch and it got stuck and try to move the truck but I didn't. Call range rover dealer he given instruction how to disengage it. After that whenever parking brake switch is depressed it make a big noise.

Richard :

Usually the noise and fault is due to worn/corroded parking brake shoes or they are mis adjusted. Since you did not have any recent brake work done then it is most likely not an adjustment problem. If the pakring brake is jammed there is a proceudre that needs to be done with a Rover IDS which is the diagnostic tool we use. Then once the shoes are repaired the electronic parking brake can be properly tested to see if the actuator or control module has been damaged./

Customer :

I took it to the dealer he said its actuator. I need the detail instruction how to replace the actuator.

Richard :

The shoes most likely damaged the actuator. The actuator is not that eay to replace as it is about a 3 hour job but I will upload the repair procedure.

Richard :

Actuator

Customer :

Do you have the parking brake shoe replacement procedure so that I can try that to see if the parking shoes are bad or need adjustment.

Shoes

Customer :

I took out the wheels today to see if the shoes are worn out. One side shoes are completly worn. Only the h are metal shoe part is there. The other side shoes are fine. I think thats the problem. I got shoe pad from Napa and they don't have adjuster on the brake shoe. The original has extra assembly, a moveable flang for parking cable rivited to the brake shoe. Is this come with brake shoe or have to reuse the existing one.
