I was thinking of using one for the front, mainly for a parking brake....
Bad idea? good idea? Thanks Andrew |

Bad idea. The fluid is left under pressure and will eventually leak past the cups, and your car will go off without you.

I was just looking at these yesterday. I think the electric ones for Drag Racing aren't meant to be locked for more than a minute or so. Jamar Billet makes a mechanical one.

Don't think they're legal for use as a parking brake... But great for doing burnouts!

A car the Cap'n built a long time ago had them. They would hold fine until the brakes cooled, then you'd watch the car start rolling. Sorry, bad idea.

I wouldnt want to hold pressure to the brake system while the brakes cooled anyways, It'll warp the rotors.
A mechanical one might work... Keep in mind I would never use this without the car being in gear. |

The car I am getting had this on it. Dave said it didn't work and yeah after they cooled the car went for a ride by itself. He had a big wooden chock in the trunk. MAD Ghetto HAHA!!!

putting the car in gear does not always work...clutch slippage, car popping out of gear....if I was your dad, I'd suggest you do it correctly as long as you live there..homeowners insurance wouldn't like that claim (IMG:http://www.914world.com/bbs2/html/emoticons/wacko.gif) |

Dad was the one who said a line lock would work...
But I havent used my parking brake in a year! the little button was stripped.... I'd like to throw larger brakes on the rear to match my bigger tires... and I dont know of any calipers that could work.. Except putting on a separate caliper for use as a parking brake. That COULD work.. Andrew |

Not another one! Group: Benefactors Posts: 4,526 Joined: 1-March 04 From: San Mateo, CA Member No.: 1,743 |
The meta question here is: "I'd like rear calipers with bigger pistons AND a mechanical handbrake. What do I do?".
There are lots of cars with rear disc brakes now, and all of them have to have a mechanical handbrake. Has anyone tried looking at other cars for adaptable rear calipers? There should be quite a few that would work. The cable-operated spot calipers are nice, but add weight and now you have two calipers per rear wheel. The 911 setup is very nice, but fairly difficult to adapt to the 914. Caliper mounting adapters are not rocket science, so adapting almost any caliper should be possible (within reason). I need to take a look at my FIAT's rear calipers, since it has rear discs. Maybe if it ever stops raining... Another angle: how hard would it be to manufacture new larger rear pistons, and is there enough meat in the stock rear caliper to bore it out? I'd guess no more than 2-3mm would be sufficient to balance the usual bigger fronts used. |

Some (maybe even most?) discs with parking brake actually use a little drum brake inside for the parking brake. Seems like I've heard of someone adapting a 911 setup like that to a 914, but I don't think it was easy. The other problem is many modern cars use a floating single piston caliper, which would also be difficult to adapt to a 914.
I know the front of an 87 Subaru GL-10 has a caliper with integrated parking brake (yes, I said front). But it's the floating type, and it's big and heavy. I saw no easy way to fit it on a 914. |

Most available today are sliding caliper rather than 2 piston, including the "high end" cars, Audi, Mercedes, etc. Not until you get to the top of the line cars do they go opposed piston.. then those might be ridiculously large for the 914. Why not just fix the stock ones? Use a larger diameter rotor and use an adapter to move the stock caliper further out radially..?? |

Why not just use a little caliper that works by cable on either side that works off of the normal rotor? I seem to remember seeing this somewhere? Maybe it was an MSDS thing?

mount a disc small thin e-brake from newer gm light duty trucks on the outside of the cv joint at the tranny, and fab up a mount for the cable caliper.
