Using a Line Lock as a Parking Brake?

I am interested in purchasing the K-Sport Big Brake Kit for both the front and the back but by doing the rears I will lose my E-Brake.

I was curious if a line lock could be used a parking brake. I would rather not have to try and fab a wilwood parking caliper.

People have done it, just google 'line lock parking brake'. Here's one site for example: http://www.gmcmotorhomeinfo.com/BRKLOCK.html, of course that's on an RV.

Illegal for a street car. you must have two means of stopping the car in the event the main hydraulics fail. the line lock uses the pressure generated from the master cylinder and locks the fluid in place.
But if you blow a brake line or the MC goes out (or simply runs dry from a leaky caliper), then you have zero brakes and the line lock doesn't do anything.

That's why every car you see on the road today has either dual master cylinders and/or a mechanical parking brake that doesnt' rely on the hydraulics in the event of an emergency.

Are you still producing your rear kits? If you are do you think it would be possible to purchase the K-Sport Z32 rear kit and use it in conjunction with your kit?

Thanks!

Probably not.
the Z32 stuff doesn't bolt directly up to the Max, but then again I use a Z32 rotor and a relocation bracket to fit the stock Z32 caliper... so it may be possible to use their stuff in conjunction with my relocation bracket.


but I wouldn't recommend it. I won't touch K-sport stuff with a 1 ft pole.

Ksport = poser junk IMO.

Btw, you can buy wilwood rear calipers with a mechanical ebrake pull. They're probably not much better than stock (depending on piston size, of course), but they look a bit nicer and still have an ebrake function.

probably would need to fab a bracket though.

I wonder if you could rig an aux MS (really small one) and tee it into the rear lines with a one way ball check valve?

still functions the same. what happens if the rear brake line is the one that blows? no brakes, no parking brake. crunch.
