Overview
The Crown Automotive 5093542AA is a passenger side rear brake caliper for the 2003–2006 Jeep Wrangler (TJ) and 2004–2006 Wrangler (LJ).
Rear calipers on the TJ and LJ are handed, and this one is the right-hand unit, listed at the rear right position. Crown Automotive supplies it without pads, so the pads from the vehicle or a new set go with it.
Crown is a long-running maker of Jeep replacement parts with more than 8,000 part numbers. The 5093542AA is marked as a direct fit, and it pairs with a separate driver side rear caliper for the other wheel.
A caliper is handed, so right-versus-left matters on a TJ or LJ just as it does on any vehicle. The 5093542AA is the passenger side, mounted at the rear right. Replacing only one rear caliper is possible, but many owners renew both so the two sides behave alike. Since pads are not included, checking their thickness and the rotor surface while the wheel is off is a sensible part of the same visit.
Key features
- Passenger side rear brake caliper
- Rear right position
- Supplied without brake pads
- Marked as a direct fit
- Covers Wrangler TJ and LJ
Caliper wear and service
A rear caliper clamps the pads against the rotor each time the brakes are applied, so its piston seals, slide pins and bore take constant heat and moisture. On a TJ or LJ, a caliper that drags can cause the pad to wear quickly on one side, pull the vehicle slightly during braking and heat the wheel after a drive. Check the slide pins for free movement and the boots for splits when the wheel is off, since a dry pin is a common cause of uneven wear.
When choosing a caliper, match the position and side before anything else, because the rear units are handed. Brake hose condition matters too: an old hose that has swelled can restrict flow to the new caliper. Many owners pair a caliper with fresh pads, the rotors checked for thickness and runout, and new hardware clips. Bleed the system after the job and test the pedal feel in a quiet area before driving on the trail.
- Check slide pin movement and boot condition
- Inspect pads and rotor thickness while the wheel is off
- Replace hardware clips with the pads
