Has anyone installed the front, inner brake shields? They weren't installed from the factory but were later suggested as a preventative measure in a TSB regarding uneven inner pad wear, pedal vibration and rotor warping.

I bought some to install when I do the hub/brake swap. Just curious to know if anyone has them on and if they've made any difference.

Not sure if that applies to the LNF but they are recommended for the other 5 lug models. There's two different sizes. I'll take pics of the shields when I get home from work.

This bulletin is being revised to clarify the vehicles involved in the model and parts information. Please discard Corporate Bulletin Number 08-05-23-003A (Section 05 -- Brakes).


--------------------------------------------------------------------------------

Condition
Some customers may comment on a brake noise and/or pulsation on brake apply. This condition can be more frequent if the customer resides or travels on dirt/gravel roads and usually occurs within 11,300 km (7,000 mi) to 16,000 km (10,000 mi) intervals.

Upon investigation, the technician may find that there is considerable difference between the front brake outer and inner pad thickness.

Cause
This condition may be due dust, dirt, and debris intruding between the inner brake pad and rotor.

Correction
Road test the vehicle and confirm that the brake noise and/or pulsation is coming from the front brakes. If it is determined that the noise is coming from the front brakes and there is a measurable difference between the outer and inner pad thickness, remove the front wheel bearing/hub assembly following published SI procedures, remove the bearing/hub-to-steering knuckle spacer and replace the spacer with a splash shield on each side.

Replace the front brake pads and follow the procedures outlined in Service Bulletin 00-05-22-002J for servicing the disc brake rotors.

i know this says excludes SS models but there are 2 different splash shields. one for 296mm and one for 256/280mm rotors. Doesn't the LSJ have 296mm rotors?

I am putting on the LSJ/JL9 brake system. I bought the ones for the 296mm rotors. they were under $5 a piece. if they dont end up fitting/working, oh well.
