Pawlik Automotive 2008 Range Rover Sport, Parking Brake Module HD

Bernie Pawlik, Pawlik Automotive Vancouver, BC http://pawlikautomotive.com (604) 327-7112 Mark: So we’re going to talk about a Range Rover Sport and you did some work on the parking brake, what was going on with this vehicle? Bernie: Well, the vehicle came to our shop with a warning light on the dash and a rather irritating bell ringing in the vehicle when you’re driving the car, every time you stopped at a light and then go to accelerate the warning chime would come on. There’s a warning light on the dash for the parking brake and then there’s an actual warning service parking brake system. So that’s what was going on with the vehicle. Mark: So what did you do to try and diagnose this? Bernie: So being an electronic issue, at least electronic warnings and Range Rovers being a sophisticated vehicle, we plugged out diagnostic scan tool into the vehicle and retrieved one trouble code for an overheated parking brake module and as soon as we cleared the code, the code had returned immediately, so we knew there’s a defect in the module based on that particular symptom and it was basically a matter of replacing the parking brake modular to solve the concern. Mark: So the parking brake module, is that just an electronic part or was there mechanical parts as well? Bernie: Actually, it’s a rather involved piece. It sounds like it’s just an electronic module here but when I hear the word module, I think a little electronic piece but the one actually is, there’s lots to it. I’ll show, I’ll share some pictures. So this is the parking brake module. This is the electronic and motor portion of the module. This module actually has, it’s electronic plus it has the actuator motors and the cables as well and in the next photo I’ll show you, this is the actual, this is a larger view of what you get when you buy the part. This is the old one removed from the vehicle. You can see there’s two large cables, one on each side. These go up to each wheel and actually link up to the parking brake shoes and there’s a third cable which is actually an emergency release. So should the electric motors fail for some reason, there’s actually a way you can manually pull a handle in the vehicle and release the parking brake. But in the case of this vehicle of course, that didn’t matter because the defect was in the electronic module itself. And while we’re just looking at pictures, here’s a 2008 Range Rover, it’s the vehicle we serviced. Mark: Ok, so that sounds like a lot of work to replace. Is this a pretty common failure part? Bernie: It’s a fairly common failure part on these things. We don’t do a lot of them but they do fail from time to time and the fact that the dealer stocks it is always to me, an indicator that it’s a common part. We have done a few of them from time to time and it is a lot of work to replace. The module was buried up underneath the vehicle, there’s covers and things to be removed to get to the module and then the cables of course, have to be remove
