Does anyone know where I can get front calipers for a 2003 Workhorse chassis? The auto parts stores don't have listings for them and my favorite website RockAuto.com lists only the rears. Any help is appreciated.

Which Workhorse chassis?Here is site for Wagner. Once you know what chassis you can find where to get them.Wagner Brakes

Check the WH web site.W20/22 chassis had Bosch brakes. Which was a problem.Caused a reacall on them.

Any help is appreciated.I would first check with Workhorse or one of their authorized service centers to see if the caliper recall has been completed, or if you are the registered owner with Workhorse all the information will be on their website.If the recall has not been done, it will be completed free of charge along with anything deemed collateral dammage.

Good info. I will check into the recall. It's not mine, a friend's that I'm working on. Thanks everyone.

Try this site (oemys-performance.com) it has some part number crosses for both P and W series chassis. I used it to get a number for a caliper for my P chassis from Autozone this summer.

So does AMP own Navistar as well?

Replaced the calipers and all is well. No more pulling and no more cooking brakes. Thanks for all the help everyone.

I thought Workhorse was now owned by AMP Trucks. Just when did Freightliner buy them???
In March of this year AMP did indeed buy the Workhorse brand. Freightliner (Mercedes) has never owned Workhorse.

Yup. I got it figured out that it's the P chassis with Bendix brakes. I'll be doing the calipers on tomorrow and hope it takes care of it.

I have Bosch Calipers and have replaced all 4, the fronts are the same as the rear, they are 66mm pistons and used on many trucks and should be available at any truck or RV dealer.

One quick way. Look see if you have coil springs up front with air bags inside. Than it is a P chassis.

According to OEMY's website the Raybestos caliper # is for all 4 corners. Picked up a couple today and will be putting them on tomorrow. These calipers take the 184 pad so I should be all set.
