My brake calipers froze!! Nothing like driving to work and having the Jeep pull to the left when you hit the brakes and the right when you don't. Not to mention the smell is just like an electrical fire. I though "ahhh Man whats wrong now." We had a trip to Three Lakes set up with some Jeepers from the Tampa area. Friday I changed the brake line and cleaned the caliper, that did not work for long. We took a trip to visit my family on Saturday morning and most of the afternoon we had rain. Sunday morning. A quick Pizza for lunch and I started the 1 hour job of changing the front calipers...... 4 hours later I finished. The new calipers had some burrs in the banjo threads causing issues with the fitting. O'Reilly's help me out with some thread cleaners and we are now good to go. This is a how to video and not meant to be a definitive guide to caliper replacement. The MightyVac made bleeding the brakes a breeze.
9/16 , 1/2 3/8 inch sockets & Wrenches
Jack stand and Jack.
Brake fluid. DOT3
Parts: 18-4340S and 18-4339S
1. Lift and secure Jeep.
2. Remove tire.
3. Loosen calipers slide bolts.
4. Loosen and snug brake hose on caliper.
5. Remove slide bolts and leave brake hose on.
6. Prep the new caliper. Make sure the banjo bolt hole threads are clean and free of burrs. Some remanufactured calipers may need a good thread cleaning before the banjo bolt goes in. Don’t let debris go into caliper.
7. Remove Banjo bolt and place NEW copper washers on each side of brake hose before placing on new caliper. Make sure the area is clean. Make sure ridge and notch are aligned properly. Snug the bolt enough to stop fluid from leaking.
8. Put brake shoes on and place caliper into place, tighten slide bolts.
9. Tighten Banjo bolt. 22 fpds. DON’T over or under tighten, or you will have leaks.
10. Push brake pedal to compress caliper.
11. Bleed brakes.
12. Put the tire back and go for a test drive.
Brakes are important to do correctly, failure is not an option.
If your net getting a good pedal then re-bleed the brakes.
Bigger tire may require bigger brakes.
Look into better rotors and calipers if needed.
