WJ Teves Calipers Chronology
2000 WJ, 4 liter, 2WD, now with 105 K. 96 K: Replaced both front rotors, due to warped rotors - judder in steering wheel - but *never* smelled hot brake pads. 98K: Left front caliper (driver side) exhibited excessive dragging (smells and vapor). Replaced *both* front Teves calipers. 104.7K: Left front caliper (driver side) exhibited excessive dragging (smells and vapor smoke). Replaced left front brake line. 105K: Today - Left front caliper (driver side) exhibited excessive dragging (smells and vapor smoke). Stopped, let the caliper & rotor cool, and drove home (10 miles) with no further incident. WTF! Does this mean that I need to remove, lubricate the caliper/brake pad slide areas with Neverseize, every time I change the engine oil? Anyone have a better fix? -- Ted Borck |

I believe it means you must replace your valve cover gasket.

They (DC) makes a kit to replace the Teves with Akebono units.

The pad I used at 76K is from the '03 - end of the run. I don't know if Akebono supplied the calipers during regular production but the '03 and later pads fit the Akebono calipers. I don't lube the slides except at pad service. I do use oil on the studs and only torque to 65 lb-ft (no to start the lug nut torque thread again). Now at 113k and will probably make it to 130 based on the remaining pads. Here is a PDF of the TSB. reboot -- NewsGuy.Com 30Gb $9.95 Carry Forward and On Demand Bandwidth |

Ted Borck > wrote: #96 K: Replaced both front rotors, due to warped rotors - judder in #steering wheel - but *never* smelled hot brake pads. Wow. You made it to 96K before they warped? Mine first warped at only 11.5K. #98K: Left front caliper (driver side) exhibited excessive dragging (smells #and vapor). Replaced *both* front Teves calipers. With what? Did you replace with Teves again, or Akebono? New or rebuilt? #104.7K: Left front caliper (driver side) exhibited excessive dragging #(smells and vapor smoke). Replaced left front brake line. # #105K: Today - Left front caliper (driver side) exhibited excessive #dragging (smells and vapor smoke). I think your piston boot(s) burned off. Did you see any glowing ash dropping from the calipers while they were smoking? Mine burned off when I got stuck in traffic. I could feel the heat from the wheel just standing next to it. Pull off the pads from the calipers and check to see if the rubber around the pistons is still intact, if they are not, dirt will get into the resin pistons and the resulting damage will cause leaks. At the very least, replace the rubber boots on the Teves calipers. #Does this mean that I need to remove, lubricate the caliper/brake pad #slide areas with Neverseize, every time I change the engine oil? # #Anyone have a better fix?

It IS possible that your 'new' Teves caliper is bad. Can you do a
warranty exchange? Also, I'd douse everything in brake cleaner prior to reassembly. tw __________________________________________________ ___________________ 2003 TJ Rubicon * 2001 XJ Sport * 1971 Bill Stroppe Baja Bronco "There is a very fine line between 'hobby' and 'mental illness'."

Do you own a torque wrench for the wheel lug nuts?
That's about the only other thing that causes warped rotors, except for the TSB that was mentioned that says the teves caliper is a POS and doesn't work, another brand is needed....

It doesn't hurt a bit, to open the bleeder and waste the contents of the
piston when replacing pads. Especially when the likely alternative is to force all that old fluid out the master cylinder and all over your (painted) inner fender.

Hi Ted,
No one has ever told us what was wrong that caused the rotors to wrap, but Daimler replaced both the rotor and calipers under warranty: http://www.billhughes.com/WJCaliber.jpg They were probably initially machined out of align.
