I did some more calculations and I feel safer adding this gusset. it is way overkill but it helps in the load sharing of the cast rear end fins.

You're drilling and bolting the unit to the rear housing with grade 8 I assume. Where did the rotor and caliper come from? :confused:

absolutly! these are grade 8 armor coated over cad plated hardware. and like i posted in the 10 bolt post these are not from any donor cars. i purchased the rotor and caliper from independent manufacturers and replacement caliper pads are available. i have them already.

as stated in the 10-bolt post, i worked out a generous safety factor with the calculations of the stresses on this device. i installed mine on my rear end for good now. i stood on the aluminum parking brake caliper and jumped up and down on it repeatedly. i weight at least 225 lbs :eek:
and it did not budge, it does not represent the worst case senario of 400 lbs on a steap hill but it gave me some reassurence of my estimates. when the car is running or i install it on another one of my cars or some gets one from me and installes it i will have a real application test to report.

I just recently recieved my kit from Pete, and it is definately well-built, quality piece. I would reccomend it for anyone who is using rear disc brakes, and doesnt want to use an inner drum type parking brake. It would also be nice for pro street cars with lots of backspacing.

Pete, what do you use for a cable that goes from the treaded end of the cable off the pedal, to the caliper...just wondering what worked for you. Thanks

thanks for the complements. i have not finished it yet, just trying to keep up with the production of these things. but the way i figured on putting a turnbuckel on the threared rod attatched to the front brake cable, then measure the distance with a wide curve to the aluminum parking brake caliper. there are endless cable possabilities but you want to make sure there is a return spring to keep the caliper pads off the disc when you are not appling the parking brake. i will post as soon as i set mine up. graemlins/hurray.gif

Are you, or are you going to sell this thing also?

yes i have had a flood of people that have been needing this thing, it is for sale, but i do not want to promote it in this forum. all's i'll say is check out my web page in the sig. I don't want to be obnoxious with this, its just that i put a lot of work into this and think that people can really benefit with this option that otherwise is not available anywhere.

update on progress. i have installed the rear into the frame now and am checking for clearences. befor putting the springs in i lifted the rear until the first point of interference made contact. the rotor and caliper would hit the rear crossmember first. i'm not so sure the springs would allow it to hit thought, they might bottom out at there solid height before the rotor would hit but, i wanted to make sure the rotor could never hit the frame. so i removed the rubber bumper that was mounted in the middle on the frame and replaced it with a steel bracket. this bracket will make contact with the rear befor the rotor can hit the frame. it also clears where the caliper cable will be running. i doubt the suspension would or could ever compress so much as to hit this bracket, but if it did i feel better knowing that the rotor will not hit the frame.
