The brake upgrade article in the tech section was a big help in directing me towards some improved braking options on my '93 4x4 Ranger.
article: http://www.therangerstation.com/how-to/wheels_and_brakes/ford-ranger-brake-upgrades/
So far my upgrades include
I'm looking for any more low-hanging fruit and I'm wondering if it were possible and advisable to increase the size of the rear wheel cylinder for the 10" drum brakes. Standard equipment units have a 15/16" bore and it looks like the F-150's had a 1" inch wheel cylinder with what looks to accept the same fittings and installation size though the brake lines would be plumbed a little different. I'd need to check on the bore centers to ensure the actuation rods aren't cocked as this would be a deal breaker requiring work on the backing plates to get the shoe supports properly aligned.
My back of the napkin calculation tells me I can get an extra 200lbs of force on the pad at 2000psi (guessing this value). Has anyone done this upgrade? How did it perform? I think the rear will have a slight actuation delay do to the larger bore but would come in harder under severe braking. I don't pull much in my truck but I do run 33x12.50 mudders which I want to overcome the loss of brake performance from the big heavy tires. Like I said, just looking for anything left that offers a slight improvement without making the truck unpredictable (easily locking up the rear under empty bed conditions)
Love to hear your thoughts on pumping some life back into this old truck.
