Disk Brake swap. 84 front end onto 68 C10 - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

To do the springs. Use a spring compressor. They will usually loan one at the LAPS here in the states. The factory Booster and MC from a 71 up will work but the bracket and rod is needed. It does stick out from the firewall a lot. The drum set-up has a distribution block but the disc is a proportioning valve unit and you will need it.

Digging this one up from ages ago!

I have been collecting the parts to start the swap. Finally began disassembling yesterday.

Pulled the front clip.

Cross member and suspension fully removed.

Ran into some wierdness. Not quite sure what year the disk front end I have is from. Made the assumption it is a 1975.

I had two center link sections in my shed, and I got confused which one belongs to the disk front end. One of the center links had a smaller diameter drag link. The 68 had a larger diameter drag link, I definitely wanted to stick with the larger diameter drag link. So anyway, that was odd....

found a center link in the shed with the correct larger diameter drag link.

bolted the cross member in. This was really easy. Had to enlarge the side frame holes to use 1/2" grade 8 bolts. Drilled the one of four side holes from scratch. Generally very simple though.

Stopped here, as I was without the 9/16" ubolts to mount the control arms. My order arrived the next day.

Wire wheeled the springs and then zinc primered & bedlinered them.

Got the lower control arms, upper control arms, and spindles attached. Also the tie rods.

Next day I packed the new bearings, mounted the rotors, and brake calipers.

Also mounted the power brake booster.

Noticed the booster is interfering with the air filter/snorkel thingy.... not sure what to do about this.

At least the bottom side is pretty! I have been driving it for a week with the front bumper off because I like looking at all the shiny bits!

Having trouble getting used to the power brakes. I keep my foot high on the pedal, use to using my weight to push it... Definitely a worthwhile upgrade!

oh, I modified the air intake/snorkel to offset the carburetor hole so that it cleared the new brake booster. Some shabby welds there.
