There are many reasons, but the biggest reason is better braking. The main reason you have better braking with disc brakes is because they do not require maintenance like drum brakes do. There’s no springs to break and no adjusters to rust up. The main problems with drum brakes is that as the drum wears the shoes don’t fit as well. Even if you put new hardware and shoes in them they still don’t work that great and the first time you get in the mud they can get clogged up. None of those problems exist with disc brakes. By eliminating all of these problems the effect is much better and more reliable braking. We have had many people tell me the overall braking performance is greatly improved.
With my standard disc brake kit there is no parking brake. This kit was designed for off road use. If you want a parking brake then I do offer special calipers for $200 more that includes all the hardware to connect your existing emergency brake cable to. It is from a 1976 Cadillac Eldorado and is the same caliper as the rest of my kits except it has a lever on the side that allows you to hook up an parking brake cable that manually moves the piston in to hold the vehicle in place. If your state requires an inspection with functional parking brake then you may want this.
No my kit is balanced meaning that it takes the same amount of fluid to actuate the caliper as it would the wheel cylinder in drum brakes. It works best if nothing else is changed.
I offer two choices for regular calipers. The JB6 (standard) and JB7 (heavy duty). The difference is the bore size and amount of fluid required to activate it. The JB6 is recommended for most people. The piston is 2 15/16″ diameter or 2.95″. The JB7 is 3 5/32″ or 3.16″. The bigger piston can clamp harder, but also requires more fluid. My kit with the JB6 caliper is designed to work well with your factory master cylinder. If you use the JB7 caliper it may require you to change to at least a 1″ bore master cylinder. Most 3/4 ton and 1 ton trucks will not have a problem with this.
It works with most depending on backspacing. It will work with all 15″ rims with 3″ or less backspacing. It works with most that have 3.5″ or less. It will not work with most that have 4″ or more. Steel wheel have more clearance than aluminum. I have seen people grind on the calipers for a little more clearance without a problem. All 16″ and bigger wheels will clear except dually wheels.
Yes I can do custom kits. If you want a kit but already have some parts we will just send what you need. Just choose the desired options on the product page.
We keep a large inventory of parts in stock and ship the same day or next day depending on when the order is placed. We ship by priority mail so you should have it in 2-3 days. Don’t worry if you only get one box before the other. Sometimes one box will get delayed a day by USPS, but we always ship both out the same day.
If for any reason you are unhappy with your purchase return the unused, rust free, and unpainted kit to me for a refund minus a $30 charge for shipping and handling.
Yes Canada is an extra $150 and other countries are $230
No I don’t have detailed instructions. This is really simple to install for anyone who understands how brakes work. Only word of advise is that most of my kits require the rotor to be on the backside of the hub.
Converting to disc brakes does not change the width of the axle in any noticeable way. Most of the conversions will make zero change while a few of the kits will change the width by the thickness of drum which is generally less than 1/4″.
No there is no need to change the wheel studs. Your drum is about 1/8″ thick and the rotor is about 1/4″ thick. The end result is your factory studs will be 1/8″ shorter and that should not be a problem. There is one exception and I include new studs with that kit.
