I chose to use Toyota pickup (minitruck) parts to swap onto the front axle to replace the original drum brakes.
|Next, because we are using birfields from a minitruck, we must grind on the housing to get the larger/stronger birfield to fit. You will need to grind a little off of the top and bottom directly to the outside of the kingpin hole. Test fit the birfield periodically to check your progress. Keep in mind that you need to go about 0.040" over to compensate for how much the ball compresses when the knuckle is torqued down.|
|I used Napa #38878 for my flexible brake lines. I probably wouldn't do it the same way again. I would keep the short piece of hard line from the
caliper and the bracket on the backing plate so that the brake line is actually "locked" from turning in the caliper. My brake line setup is commonly used without problems, but it seems a little hoaky because of this.
Install the proportioning valve on the line that goes to the rear brakes. You will need to get the fittings and flare the tubing to install it. I chose to install it right next to / under the booster. I bought a short section of already flared tubing with fittings at AutoZone so that I would only have to flare one end.
I chose to use a booster that I had laying around. It is from an '89 4 cylinder 4runner. The master cylinder is from a '95 4runner with a V6. Everything bolted right up and took only minor adjustment to get correct. The brake lines even ended up in the right place on the MC without bending the lines!
