WARNING!!! THIS KIT IS INTENDED FOR OFFROAD USE ONLY NOT FOR HIGHWAY USE!
This kit is designed to utilize 2004-2006 E150 rotors (5 lug) with 2005-2010 mustang rear calipers. you will need to source rotors, calipers, brake lines, and proportioning valve separately for this kit. it is also wise to swap out your residual valve for the correct size for rear disc brakes (2lb) over the stock drum size (10lb). supplied below are some part numbers for reference that was used on the test truck and are still in operation today.
Part Number Reference
18B4927 & 18B4926 (bracketed s197 mustang brake calipers)
950.61501 (stop tech braided brake lines)
BLF-31B (bubble flare to inverted flare adapter)
PRT5697 (stock 2004 E150 rotors)
633-54192L & 633-54192R (drilled and slotted rotors)
260-8419 (wilwood proportioning valve)
260-13783 (wilwood 2lb residual valve)
Install notes:
stock s197 brake hoses will not work! it puts the hose in a bind anyway you try to route it, also runs into leaf spring clearance. to run the stop tech braided lines, you will need to use the bubble flare to inverted flare adapter or it will leak.
you may need to replace your 10lb residual valve with a 2lb one which is meant for rear disc brakes. not doing so may cause the brakes to drag. an adjustable proportioning valve will get your brake bias dialed in once installed.
make sure when you install the calipers that the bleeder screw is facing up and not down. it will not bleed correctly causing brakes to be soft or fail completely. you may have to flip the caliper sides (driver side to passenger side and vise versa) to get the bleeder screw facing straight up. brackets were designed to point towards the rear of the truck.
