MC from a 78 Corvette,rear calipers from a 84 Cadillac Eldorado(has parking brake in it)Caliper mounts from TSM.
That's what I have on my 71 Blazer anyway.

This is the best pic of my Corvette MC I could find

How does that parking brake work? original cable or??????

Well I'll tell ya, it is of course your own preference.
I use stock MC's and never had a problem. A good amount of the kits we have sold we have never installed a MC.
But of course you are probably swapping everything over to disc and from what I have heard and read the corvette one seems to be what the guys on here install, when going from drums to disc..

I installed a kit on my 3/4 ton and have yet to have a braking issue. It is also my daily driver
As for the emer brake we sell the bracket that attaches to the caliper to work with your cable.

There are a lot of options out there but thought I would jump in

Here are a couple of shots of it installed on my '72

would u use the prop. valve off a 78 vette too?

If i was going to upgrade from all drums to disc, I would probably just use a 3/4 mc or hydro assist. But thats what i have laying around..

Some people swap to corvette or other style, and some don't..
Mainly a trial and error item on our year trucks

I'm just running a regular old MC with booster for drums and I dont have any problems with mine at all. I have been driving it like this for about 8 years. I do change the pads regularly and get the cheaper pads. It stops great.

I used my orig. brake cable.I had to shorten it by about 2" though.I also had to make some small mods to the Eldorado e-brake bracket.
Problem I have found though is the orig e-brake pedal does not have enough travel to FULLY engage the e-brake.
It does engage,but it needs a smiggin more travel to have full e-brake pressure on the rotor.

i used the master cylinder and proportioning valve off a 78 vette on mine. also used the rod but had to turn down the end that goes in the booster just a few thousands as it fit too tight. also had to take about a quarter inch off the length of the rod. havent got it on the road yet but heres a pic and comparison pics of vette vs stock pieces.

[Budweis]

heres a pic comparing the rods, the vette rod being on the left

[chevy69er]

Why did u change out to the vette rod?Would i have to do that if i use vette mc and prop. valve?

[Budweis]

changed it because where it goes in master cylinder is different on vette mc and seemed like easier route to modify vette one as its two piece rod.
