If you're looking into a semi floater 14 bolt disc brake conversion , you probably know that already those stock percussion are basically weighty anchors that don't do much for the stopping power. Whether or not you're running a late-80s Chevy or a more modern project truck, that 14-bolt semi-floater (SF) axle is a solid piece of hardware, but the braking technology it came with is usually stuck in the particular dark ages. Eliminating those massive, clunky drums and replacing them with disks is among the most gratifying upgrades you may do for your rig.
Let's be honest, working on brake drums is the total pain. Coping with those small springs that love to fly across the particular garage and attempting to get almost everything adjusted just right is enough to make anyone wish to change the whole axle out. But given that the 9. 5-inch 14-bolt is actually a pretty excellent axle for half-ton and three-quarter-ton builds, keeping it and upgrading the "whoa" factor makes a large amount of sense.
The reason why move away from the stock drums?
The greatest reason most of us take a look at the semi floater 14 bolt disc brake conversion is definitely simple: performance. Drum brakes are okay for traveling around town, but the second a person add bigger wheels, some heavy equipment, or a trailer, they start to show their weaknesses. They get sizzling, they fade, and they just don't have that bite you need in an emergency.
Discs are much better in shedding heat. When you're coming lower a mountain move or navigating a tricky trail, a person want a brake system that remains consistent. Plus, maybe you have tried to clear mud out of a drum brake assembly? It's the nightmare. With cds, you just spray them off along with a hose plus you're good to go. It's also way easier to inspect your own pads for use through the wheels than it will be to pull a giant, heavy drum away from just to see how much footwear life you might have still left.
Comprehending the semi-floater vs. full-floater
Before you move ordering parts, you've have got to be sure you actually have the semi-floater. The full-float 14-bolt is the one with the huge hubs sticking out by means of the core wheels. The semi-floater offers a flush axle flange where the particular wheel bolts on, similar to a regular 10-bolt or 12-bolt axle.
The semi floater 14 bolt disc brake conversion is specific in order to this axle since the way the brackets mount is various from your heavy-duty full-floater. You're dealing along with a C-clip axle design generally, which means the axle shaft itself carries the weight of the vehicle and is held within at the differential box. This matters whenever you're choosing your own bracketry and foreseeing out your brake disc spacing.
Exactly what do you really requirement for the exchange?
You may usually look for a package that has almost everything, or you can piece it jointly if you're the fan of striking the local junkyard. Most guys go for a blend of both. You'll definitely require a set of heavy-duty mounting brackets—this is the particular heart of the semi floater 14 bolt disc brake conversion . These brackets bolt onto the four-bolt flange with the end associated with the axle tube once you've removed away the old carol hardware.
Intended for the rotors, a lot of people use front brake discs from a 3/4-ton 4x4 Chevy. They're thick, cheap, plus readily accessible at any kind of auto parts store. For the disc brake calipers, the common choice is the The cadillac Eldorado rear calipers if you need an integrated parking brake, or just standard Chevy front calipers in the event that you don't treatment about the e-brake.
Don't forget the smaller sized things like new brake lines. Your older hard lines won't just "reach" the new calipers. You'll need some wrapped stainless or silicone flex lines to bridge the distance from the axle housing to the particular caliper itself.
Having the job completed in your driveway
Doing a semi floater 14 bolt disc brake conversion isn't specifically a five-minute work, but it's totally doable over the weekend break. You start simply by jacking up the rear end plus getting it on some beefy jack port stands. Safety first, right? Once the wheels are away, you've got in order to pull the difference cover to get to those C-clips. This is an excellent time to modify your gear oil anyway, so don't be too frustrated from the mess.
Following the axle shafts are pulled away, you can unbolt the backing discs and throw all those heavy drums within the scrap pile. It's a great feeling of accomplishment simply seeing that weight disappear. You'll likely want to clean up the axle flanges along with a wire wheel to make sure the new mounting brackets sit perfectly smooth. If things aren't square, your brake systems will squeal or wear unevenly, plus nobody wants that will.
Dealing with the parking brake headache
I'll be real with you: the car parking brake is normally the particular hardest section of the semi floater 14 bolt disc brake conversion . In case you reside in a level state and travel an automatic, maybe a person don't care. Yet if you have got a manual transmitting or you really use your vehicle for truck items, you're going in order to want an e-brake.
Using those Eldorado calipers I mentioned earlier will be the "old school" way to perform it, however they can be finicky to modify. Some modern packages use a different type of caliper along with a built-in mechanical lever, or some guys even move with a drive line brake on the output of the particular transfer case. Whichever you choose, make absolutely certain you plan intended for it before you get midway through the project and realize your own truck is heading to roll lower the driveway.
The master canister and proportioning control device
One point people often ignore when doing a semi floater 14 bolt disc brake conversion will be the rest of the hydraulic system. Disc brakes need a different amount of fluid than drum brakes. If you maintain your stock master cylinder, you will probably find that will the pedal seems a bit "mushy" or that this travels beyond the boundary just before the brakes actually grab.
It's often a great idea to exchange to an expert cylinder meant intended for a four-wheel disc brake truck. A person might also require an adjustable proportioning valve. This lets you dial in how much stress goes to the particular rear versus the top. You don't desire the rear tires locking up before the fronts do, especially on a wet road or in the dirt. It's all about stability.
Is it worth the energy?
In short: absolutely. The first period you hit the pedal after the semi floater 14 bolt disc brake conversion , you'll question why you patiently lay so long. The particular truck just feels more confident. The stopping power is more linear, so you drop a significant quantity of unsprung weight, which usually actually helps your suspension work just a little better.
Servicing becomes a breeze, too. Changing pads takes about ten minutes per side once the wheels are off. No even more messing with brake spoons, adjustment stars, or those unhappy little return suspension systems. Plus, let's end up being honest, those big rotors look the lot cooler behind a set of nice wheels compared to a rusty outdated drum ever do.
So, when you're tired associated with your truck feeling like it takes the football field in order to stop, it's time to start gathering components. Whether you move with a high-end bolt on kit or the DIY junkyard setup, the transition in order to discs is an update you'll appreciate each single time a person pull out of the driveway. Simply take your own time with the particular plumbing, bleed the particular lines properly, plus enjoy the fact that your 14-bolt is lastly living in the particular 21st century.
