Brake Rotor W20 Workhorse Chassis

[jerry1]

I am going to replace all the rotors on my 2001 W20 Workhorse Chassis. What I need is information on how they come apart. Do I have to pull the axels on the rear and remove hubs and wheel bearing off the front? Or where can I find the information on this procedure for the rotor changeout?

Jerry1, the Bosch Pin Slide Disk Brake Manual may help you. Also, here is a post from someone who recently replaced his 66mm calipers with 73mm calipers. It has some pictures which may help you.

Good Luck!

This probably belongs in the Workhorse Chassis forum, but....why are you doing this?

I recently had to replace the rear rotors on my W22 chassis due to severe heat transfer of brake pad material onto the rotor surfaces...all apart of the WH brake caliper recall issue. This is all discussed in the Workhorse Chassis Forum.

While normally there might be a chance that the rotors just need resurfacing, sometimes too much material would be lost to meet the rotor specifications requirement.

I would urge caution and the input of a reliable mechanic.

Be very careful of the rear outer wheel bearing seals. Unless there is severe heat damage, it may be better to not disturb the seals when replacing the rotors. Be careful!! This not a job for the faint of heart !!

don't mess with the rotors and brake pads unless you replace the calipers at the same time. you will change the position of the pistons in the calipers with disastrous results, eg pistons not returning resulting in over heating or worse.
