This is the big brake upgrade you are looking for! You get massive rotors and brake calipers on all four corners. They look good filling out the rim. They have improved stopping power on our Jeep, it is a totally different experience. The pad set is available from Teraflex or you can get the pads from an autoparts store. They are 2015 or so toyota tundra front pads. If you have the 1" brake master cylinder you should upgrade to the 1-1/16" master cylinder. I upgraded to that and stainless lines. I don't see the need for the mopar J8 brake booster and master, the pedal feel is better than stock. Worth the money to upgrade, I would do it again, stock JKU brakes suck. 2010 Jeep Wrangler Unlimited 18" Sahara wheels with Teraflex 1.25" wheel adapters.
