Akebono calipers
 

Replaced the Teves caliper on my 2000 WJ around 5 years ago as they were seizing up with a brand new pair of Akebono calipers - now 1 of these has started to seize up.
In 35 years of car ownership this is the first one I've ever had with a seizing caliper problem.
Was under the impression the Akebono calipers didn't suffer from this problem.
Fortunately not an expensive fix.

Dual piston calipers are prone to seizing if not lubricated properly. The Akebonos are less prone to this because they have less mass than the Teves and radiate the heat faster. The pads are supported better as well and don't drag as often. Those pads spacing clips are important and should always be used. Ask me! I mucked around for 5 years trying to make the Teves work properly, then made the switch and never looked back. One important thing though. DO NOT LET THE CALIPERS HANG ON THE HOSES! If stretched, they will collapse internally and restrict the fluid bleeding back to the reservoir.

BTW, I bought my Akebono calipers on rockauto.com and returned my Teves as cores. They never questioned this, but adjusted my core credit. The rear calipers remain Teves because being single piston, they don't have problems.

Not had experience with the Ake calipers. I've continued to use the Teves calipers on our 02WJ.
I always replace the calipers when doing brake job. They charge me on average $80-$90 Cdn each after core for remanufactured
Calipers, Rotors, Pads, about every 100 - 130K km. I replaced the flex lines every other time 200 - 260k Km
WJ running at 400+K km, braking is hard and straight.
Keep an eye on your hard lines, replace them if corrosion suspect.
Flush your fluid through when doing the brakes. Fresh fluid improves the pedal feel and parts longevity (brake fluid will absorb water).
Each spring I pull the calipers off. Check the pins for corrosion, wire wheel or brush them to keep clean and smooth, and wipe out and relube the slides.
Use only brake lubricant! Other lubes will swell the slide liners and cause the pins to stick.
