Our MOD Complete Brake Kit includes everything you need to get your car stopping like it should at all four corners.
Though we’re big fans of drum brakes in the rear, we understand that rear discs brings some advantages, especially in track scenarios. But there’s a reason we like the stock brakes: the rear axle flexes. It flexes a lot. I don’t care if you have a Currie unit from a Sherman tank, the rear axles will flex. This has the effect of pushing the rotors (which are mounted to the axles) around within the caliper. So instead of having the pads gently riding the rotor, there’s a gap. This gap has to be filled when pushing the brake, which makes the whole system feel inconsistent and scary.
So what do guys do? They buy a bigger master (which moves more fluid at a lower pressure, resulting in even worse brake feel), they back it up with a brake booster (don’t get me started) and then they start asking about firewall reinforcements because they have to put so much effort into the brake pedal.
We want to use discs in the rear, so how do we overcome this problem? We opt for a floating caliper like the one found in the Wilwood D154 setup. The floating caliper effectively moves with the rear, minimizing the air gap that’s naturally created. Frankly, it’s the only rear setup we really like.
Based on years of firsthand experience, we’ve found this combination of parts to deliver the feel most customers are looking for on the street and autocross (with seldom track use). Included is a set of Wilwood Dynapro 6 piston calipers and rotors, a set of Wilwood D154 calipers and rotors, our big pin spindles, stainless front brake lines, and a 15/16″ Wilwood tandem master cylinder and proportioning valve specific to early Mustangs.
If you heard “6-piston” and immediately thought race car, you’re not alone. But we don’t recommend this caliper because “race car”, rather the simple fact that six pistons help to maximize brake pad longevity and reduce heat. It’s that simple. We also include a set of our big pin spindles in this kit. It’s a worthwhile upgrade that helps to ensure a solid foundation for your new braking system. We also include a set of DRP Hub Bearing Spacers, a small but significant addition.
For pads, we include Wilwood’s BP-20, which provides increased friction levels with extended temperature range over BP-10. BP-20 has a progressive response rate as pedal pressure and temperatures increase to provide confident, repeated stops and outstanding modulation characteristics. The unique metallic composite formulation provides an aggressive feel without the harsh noise, high rotor abrasion, and extreme dust levels associated with high metallic based compounds.
If you’re looking for a proper upgrade to your early Mustang’s braking system and want to skip the guesswork, MOD Complete is the way to go for a complete system upgrade.
