With regards to Jeep upgrades, brakes are sometimes very low on the listing of priorities. After upgrading wheels and putting in bigger 35″ tires, your stock brakes could have a very troublesome time stopping your car, each on the street and particularly while negotiating through an impediment while offroading. If you improve the dimensions and weight of your tires, you must actually think about upgrading your brakes as nicely. It should improve your confidence whereas driving and simply may make it easier to keep away from a collision or an accident. New, upgraded brakes are usually not low cost, nevertheless figuring out that your braking power has been elevated and stopping distance has been decreased is certainly well worth the funding.
There are few options relating to aftermarket brake kits, which embrace new rotors, anchor brackets, calipers and brake pads. Hottest options are Teraflex brake kits, Crown Automotive brake kits, Power Stop brake kits and Dynatrac brake kits. You will discover kits with rotors and brackets solely or kits with rotors, brackets and calipers included. New brake pads typically are included with the package, or you should purchase your favourite brand of brake pads individually. In relation to rotors, you’ll find kits with normal vented rotors, slotted rotors, or drilled and slotted rotors. Your choice comes right down to choice, your driving circumstances and naturally your price range.
After loads of web shopping and research, I made a decision to go together with Teraflex Efficiency Big Rotor Kit for each front and rear wheels. I selected normal vented rotors (I consider clean rotor floor is the best choice for a mixture of day by day driving and weekend offroading, typical rotors present highest mass which improves cooling, and with no slots I don’t have to fret about mud accumulating there and damaging brake pads prematurely), with included larger anchor brackets which allow for use of the stock calipers and brake pads. After reading evaluations on the Teraflex Big Brake Kit, I made a decision that I don’t need to change to a two piston caliper and affect the brake pedal really feel, as well as probably having to exchange grasp cylinder.
The TeraFlex JK/JKU Front Efficiency Big Rotor Kit consists of bigger 13.three″ (338mm) rotors for improved stopping efficiency – stock is 11.9″ (302mm), and larger brake caliper relocating anchor brackets. It retains manufacturing unit brake calipers & brake pads. Rear Efficiency Big Rotor Kit consists of bigger 13.5″ (343mm) machined rotors and larger brake caliper relocating anchor brackets, also retaining manufacturing unit brake calipers & pads.
When installing the Big Rotor Kit there isn’t a have to disconnect the calipers from brake strains subsequently you don’t should bleed the brakes in the event you don’t need to.
The best way this package works is fairly clever. Shifting the situation of the caliper outward just a bit accommodates the larger diameter rotor which permits for extra environment friendly warmth dissipation and better mechanical advantage in stopping. The increased clamping distance from the rotor middle leads to larger braking leverage to permit stopping distance to be decreased. It is nevertheless value noting that neither the caliper clamping pressure nor the pad-to-rotor contact space are increased (as they’re with the entire Big Brake Kit).
One thing to remember is that this Jeep JK Big Rotor Kit by Teraflex requires a minimum of 17” diameter wheels.
Disclaimer: Like I all the time point out I’m not knowledgeable mechanic, I simply try to do as much work on my Jeep as attainable. It helps me study extra about my car and avoid wasting cash that may be spent on elements and upgrades.
I take no duty for any damage or breakage which could happen should you determine to comply with these steps. You must determine in case you’re snug working in your Jeep. When you’re not, please have knowledgeable full this venture for you.
Elements and tools wanted:
1. TeraFlex JK Entrance Performance Big Rotor Kit and TeraFlex JK Rear Performance Big Rotor Kit
2. Brake Pads Front – JK and Brake Pads Rear – JK / or any model you favor
three. Disc Brake Hardware Kit or at your local auto elements store

6. Torque wrench and/or Breaker Bar
7. 13mm, 18mm and 21mm sockets
8. Brake Lubricant and Brake Cleaner
9. Wire Brush
10. Loctite Blue Threadlocker
Prepare your tools and get every thing prepared earlier than you begin the venture.
Park on a good floor and chock the rear wheels.
Carry the front axle and relaxation it on at the least two jack stands. Take away both wheels. Turn the steering wheel to at least one aspect to realize higher entry to the caliper and bracket bolts.
Clean the surface of brake fluid grasp cylinder. Take away the cap and put it in a protected place.
Place a pry bar or a large screwdriver between the surface wall of the caliper and the surface brake pad. Use the pry bar to gently push the piston back into the bore so far as you possibly can (the grasp cylinder cap was eliminated to relieve strain because you’re now pushing the brake fluid again up the strains).
Take away the higher caliper bolt using a 13mm or half″ wrench or socket. Maintain the guide/slider pin with skinny 15mm wrench to stop it from spinning.
Release the ABS line from bracket to offer it some slack.
You need to use a large C-clamp and one of many previous brake pads to push the piston all the best way again in (you’ll need this additional area to put in model new brake pads).
NOTE: you’ll need to depress your brake pedal few occasions to push the caliper piston firmly towards the brake pads after you complete this venture and BEFORE you drive your Jeep!)
Take away the lower caliper bolt. Hold the caliper securely utilizing a metallic wire hanger or bungee twine. Clean and grease the edge of the piston a bit.
Take away two bracket bolts using a 21mm or 13/16″ socket.

You possibly can reuse the inventory brake hardware, nevertheless I might advocate purchasing a brand new hardware package, which comes with all mandatory rubber boots and clips (one package per axle). Install the anti rattle clips into new bracket, paying close attention to their orientation. Put some grease into the slider pin bores, clear the slider pins and grease them as nicely. Set up rubber boots and make sure they are seated appropriately. Push the guides/slider pins into bores and verify that they move forwards and backwards freely. Grease the floor of the anti rattle clips slightly.
Assembling the bracket is far simpler on a bench or table than on the wheel. Grease brake pad ears just a bit bit as nicely, to assist them slide inside the clips simpler. Be certain that one of the brake pads on each bracket has the metallic tab – put on indicator.
Take away the previous brake rotor. Clear any rust / oxidation from the wheel, utilizing a wire brush.
Install your new brake rotor. Briefly secure it in place with one of many lug nuts.
Set up your new bracket with brake pads. Be sure to don’t switch grease onto the surface of brake rotor. Put some blue threadlocker on the bracket bolts, hand tighten first and torque bolts to 110 ft lbs.
Install the inventory caliper back into place. Torque the caliper bolts to 26 ft lbs. Clip the ABS line back into its bracket.
After finishing each side of the axle, put the wheels back on and decrease your Jeep again on the bottom.
Shut the cap on master cylinder.
Hop inside your Jeep and with the engine off, pump your brake pedal few occasions to push the caliper piston firmly towards the brake pads, till you are feeling the pedal agency up again.
Begin the Jeep and start the bedding-in procedure in your new front brake pads and rotors. For this procedure, you will have a superb stretch of street and no visitors. All brake pads have to be bedded-in with the rotor they are going to be used towards to maximize brake performance. The bedding-in process includes a gradual construct up of warmth within the rotors and pad compound. This process will lay down a thin layer of switch film on to the rotor floor. Following the bed-in procedures offered by the manufacturer will assure a clean, even layer of transfer movie on the rotor and can reduce brake judder.
My Teraflex Big Rotor Kit got here with new Hawk brake pads. Right here is the bedding-in procedure beneficial by Hawk:
After installing new pads make 6 to 10 stops from roughly 35 mph to 5 mph with average strain. Make a further two to 3 onerous stops from roughly 45 mph to 10 mph. Don’t permit the car to return to a whole cease. When accomplished with this course of, drive round for jiffy and later park the car and allow the brakes to cool utterly before driving on them once more. Don’t interact the parking brake until after this cooling process is compete.
If the front brakes carry out appropriately, now you can work on the rear wheels.
Chock the entrance wheels. Be certain that the emergency brake is NOT on.
Raise the rear axle and relaxation it on at the very least two jack stands. Remove each wheels. Remove the brake fluid master cylinder cap and put it in a protected place.
Use the pry bar once more to gently push the caliper piston back into the bore so far as you possibly can. Remove both caliper bolts utilizing a 13mm or half″ wrench or socket. Maintain the information/slider pins with skinny 15mm wrench to stop them from spinning. Grasp the caliper securely using a metallic wire hanger or bungee twine. Clear and grease the edge of the piston a bit.
Remove two bracket bolts utilizing 18mm socket.

Set up the anti rattle clips into new bracket, paying close attention to their orientation. Put some grease into the slider pin bores, clean the slider pins and grease them as nicely. Install rubber boots and ensure they’re seated appropriately. Push the guides/slider pins into bores and verify that they transfer forwards and backwards freely. Grease the floor of the anti rattle clips slightly.
Set up new brake pads within the bracket. Grease brake pad ears just a little bit as properly, to help them slide contained in the clips easier.
Once more, ensure that the e-brake is NOT on. Take away the previous brake rotor.
Clean any rust / oxidation from the wheel, utilizing a wire brush.
Install your new brake rotor. Briefly secure it in place with one of the lug nuts.
Install your new bracket with brake pads. Be sure to don’t transfer any grease onto the floor of brake rotor (clear with brake cleaner if essential). Put some blue threadlocker on the bracket bolts, hand tighten first and torque bolts to 55 ft lbs.
Set up the stock caliper again into place. Torque the caliper bolts to 26 ft lbs.
After finishing each side of the axle, put the wheels back on and decrease your Jeep back on the ground.
Shut the cap on master cylinder.
Hop inside your Jeep and with the engine off, pump your brake pedal few occasions to push the caliper piston firmly towards the brake pads, until you are feeling the pedal agency up once more.
Start the Jeep and start the bedding-in process in your new rear brake pads and rotors. The process is identical as with the front brakes.
When you finish the bedding-in process and let the brakes cool off, whenever you drive again you need to discover quick improvement throughout braking, especially for those who exchange brakes on each axles. After about 100 miles you may need to examine all the bolts just to ensure every thing is as tight because it must be.
