There have been comments over time in several forums about the foot operated parking brake, some folks love it, some folks hate it - for the latter category, have any of you tried installing one of these??

I'd be shocked if the next generation WL doesn't have this, all the manufacturers are going to it and it is on several models of jeeps already....

As far as retrofitting it to a WK2, it might be easier than other cars, but still not worth the effort and risks IMO.

WK2 has Drum-in-Hat parking brakes, they have been troublesome in the past, less so today, but just being the slightest bit out of adjustment results in either no parking brake or a parking brake that catches and applies while moving.... ....now you're going to improvise some alternative method of applying the parking brake with these kinds of brakes... ...its not hard to imagine there being lots of problems.... ....all this expense and trouble because you prefer something other than a foot pedal parking brake?

One thing on the plus side if you really want to do this, the WK2 parking brake cables are done in "T" arrangement, unlike the usual "Y" arrangement.... The two rear brakes have short cables that run to an equalizer directly inbetween them, it just pulls the cables directly together to pull the brakes, like this linear actuator does....

Most have the cables pulling at an angle facing forward toward where the equalizer is more forward at the junction of the "Y"..... ...this could be used also but there will be some cable bends awkward placement if you even have the room...

The WK2 has the room to easily mount this with very little bends in the cables.....

Thanks Mongo53, didn't know about the parking brake history so will proceed with caution, if at all .....

At one time the hand brake/foot brake was considered something you might use in an emergency. When they had umbrella handles (and similar operating variations) you could realistically use them as an emergency brake and do so with reasonable control over modulating the application force. They also controlled a full sized rear drum and could be applied with sufficient force to lock the rear wheels if you wished to. Over the years the rear drums became smaller, esp as fronts became disks. And when rears became disks many of the park/emerg part became a tiny drum inside the "hat" of the rear disk assembly. Other used a lever to push out the piston mechanically. Neither provides very good braking force. The application method more and more became a foot pedal which was generally harder to modulate than the umbrella handle was. But worse, and what's common today, is that the foot pedal can ONLY be released by pressing it ALL the way down to FULL apply before you can release it. Hardly a model for being able to modulate braking effort. The good news, in a backsided way, is that the stopping power of "parking brakes" today is generally so poor that many of them, after a bit of wear and cable stretch, are barely able to even apply the brake much less lock the wheel if any force tries to move the car. Hence today they are usually called parking brakes because they are just about useless if you need to stop the car at anything but a very leisurely pace.

The latest "improvement", a motor to pull the cable instead of the foot pedal, is another step backwards as far as any emergency use as it would make it even more difficult to do any modulating of the brake application. The only good thing that can be said for it is that it frees up foot space in a small car and because it can be automated it can be set to apply automatically anytime you shut the car off thereby providing some redundancy over what most people do.
