Has anybody done anything like this? The only reason I was considering to do this is because I can get the rotors for 70$.

Now, for arguments sake, let's pretend I'm buying this drilled and slotted rotor from Summit.Įxcuse my inexperience with these older trucks.

I see at Oreilly Auto I can get the hub assembly separate. While shopping around for a nice drilled and slotted rotor, I noticed none of them come with the built in hub assembly. Maybe they were two separate pieces and I hadn't noticed?) However, the rotors currently on the truck have the hub assembly built in.(I hope that memory is serving me well, it has been awhile since I replaced the driver side ball joints and I wasn't exactly paying attention to how the rotor was designed. I can get a pair of drilled and slotted rotors through work for around 70$, Since I'll have it all apart anyways, I was looking into some drilled and slotted rotors as a nice cheap brake upgrade to assist with braking as the stock brakes kinda suck when I have the plow hooked up and the 38.5' tires on. Its in the shop out of the weather.I'm going to be pulling my 78 FSB apart thi weekend to swap out the brake booster and passenger side upper/lower ball joints and outer tie rod ends. I just had 4 Motorcraft rotors put on with motorcraft pads. Hoses are also a wear item, and you'll get a way bigger and more noticeable difference by properly bleeding your brakes. Use the money you saved from going with drilled and slotted rotors to go with new brake hoses, especially if you car is 10+ years old and/or has 100k+ more miles. Please make sure to bleed your brake fluid. I have Wagner's new coated rotors on my HPP, and they work GREAT! I paired them with Raybestos' semi metallic pads, and the car stops on a dime and hasn't warped its rotors like the previous ones. If I had access to the software still, I'd perform some finite element analysis and some basic thermal analysis to show you the stress and heat concentrations, but I don't anymore sadly. The holes cause unneeded stress concentrations to build up on the rotors, and they cause hot spots because there is less material to help dissipate the heat better. Only reason race cars run them is to save unsprung weight (and most don't run them anymore) and 'exotic' cars run them because people think it looks cool and it sells better. Drilled and slotted rotors are not worth the money.
