Sorry, my terminology is weak. On the brake pad itself, notice how on one side it has 2 little ears, and on the other side, it has only one little ear. Make sure that the side with 2 ears, is the side that is pointed towards the ground and is the one actually sitting on the knuckle slide rail.

The knuckle is the large cast metal component that the brake caliper is mounted to, along with your ball joints. The slide rails upon which the brake pads slide are molded right into the knuckle. Over time, they get rough, corroded, or get little divots in them where the pad has been sliding for years. These little imperfects in the slide rail increase the chances that the brake pad will get stuck on the slide rail instead of returning to their normal position away from the rotor.

Luckily I had both of the pads installed correctly, waiting on the rain to stop so I can test everything out,preciate the help bud

That bit about the knuckle is super helpful, I sanded down some roughness, hopefully that'll fix a problem I've been chasing for months. Gone through so many sets off pads and calipers

I just did the procedure as well. If you have not purchased some of the permatex high-temp ceramic brake parts lubricant (white container, purple grease color). You should do so. You should lube those knuckle slides every time you are in there. This product is also used on your caliper slides (inside the boots) and can be used on the various contact surfaces between the caliper and pads to reduce the chance of squealing (it dampens vibrations that cause brake squeal). If you own an XJ, and you do your own brakes, you should have some of this in your garage.

Got it! No more clunking. It had something to do with those groves on the knuckle. Pedal feels a little softer than it used to, but before the braking sucked. All in all not too bad

New pads, rotors, calipers, soft lines, and hard lines hah. When you open up your front brakes, do you bleed your back as wellong? Garage I used to go to told me there's no need are three back and front are seperated reservoirs

As the* stupid auto correct
