Only issue with a Napa replacement is that the rotor came out in three pieces.

No idea if anything else brake wise is damaged. Pads still there but probably scraped up...

The rotor I got from NAPA was a genuine Merritor rotor.

For all of you waiting with baited breath to see if the rumors of our early demise are true they are not.

We are in a rest area in Utah for the night after around 415 miles today.

The shop was nice enough as there never was a ticket created in their shop to put the wheels back on and cage the parking brake and cap the brake line.

Slowly, cautiously increased speed. Coach runs like normal.

Only difference is the 10 to zero speed reduction with cold brakes.

Takes more pedal pushing than normal.

Back to normal speeds but bring cautious about distancing myself from traffic.

As long as it is a rear it seems to be doable to,disable one brake.

That being said the weak,parking brake requires flat ground to hold well and as mentioned here an emergency stop would be problematic

I think the rear rotor had cracked before as I noticed an increased grinding noise level recently before this 2300 mile trip.

Judging by the gouges in the one side of the rotor I assume that side had an unlevel surface and the crack must have protruded enough to grind against the hard pad.

500 miles through Vegas left for tomorrow.

Diesel went up,from $2.39 two weeks ago at the Fillmore ,Utah maverick fuel station to $2.59 today

Be safe! If you have wheel chocks, use them when parked. Just don't forget about them.

To remove a broken inner Bud wheel lug nut, you need to take outer wheel off and at the broken lug nut screw a outer lug nut on the broken inner lug nut as best you can and weld them together. Then you can turn inner lug off using impact on nut that you welded to it. I have done this many times when I worked on heavy trucks a few years ago.

Was not stripped or broken. The shops snap on gun would not remove the one nut. Thanks for the welding tip.

That good, any shop with a one inch impact should be able to remove it then.

That's what they had. A long air line probably reduced its power just enough to not rip it off

And large id line. A lot of places just use the 3/8 line that the normal air tools run on. Smart money is to put in a dedicated 1/2 or 5/8 port with that size hose to get enough air to a 1 inch gun.

I knew better but did not need to antagonize them. A hundred feet of 3/8" line with small ends doomed this.

One inner was way overtight. They got the others off slowly. Gave up. Put it together. Block the wheel.

The shop foreman was paranoid about liabity until he found nothing was in their computer and no paperwork has been done.

I was a ghost. Good

As long as I tipped the mechanic per the owner she was cool about trusting me to know what I was doing.

Made it home today at 4:30. 915 miles since yesterday mid morning.

Cold brake slow speed stopping was much harder.

Everything else was ok

Thanks for all of your help and advise. Would have been much less of a safe drive home without it.

Now I need a good source for the rotors and pads and maybe the brake chambers themselves

After I bought rotor from NAPA (they had it in warehouse, so I got it next day) for $299 or $399, I found one on ebay for like $100 new in box! Just my luck.

Took the coach in today for a Tuesday appointment and in passing their parking lot noticed two new freightliner chassis coaches with the drive rear wheels off. ,

Service advisor thinks that the rear drum brakes had the wrong parts installed new by .Freightliner as the brakes over stroked.

Can't tighten up the slack adjusters to allow full drum brake shoe contact.

2.000 and 3,000 mile new coaches that my service dealer caught on the required safety inspection.

Advisor said the chassis's serial number were quite a bit apart so there may be a lot of these chassis out there.

Apparently the Budd Alcoa wheels are no longer made for our 97 but the big fmca tire dealer who mounted mine had a single spare rim hiding in the back of his buildings and will mount my good tire on his replacement rim when the shop gets the rear tires off hopefully tomorrow,

Replacing both rotors and pads. Will see if anything else was damaged by the rotor failure.

Will save the gouged rim for someone's future use as these are not available.

Thanks again for the knowledgeable help. Got us home. Safely.

Shop said this morning that meritor only suggests the helper springs on the front axle?

Plus they had to pull the rear hubs as the rotors bolt to the hubs?

No access for power tools without pulling the hubs and then replacing the seals?

I had helper springs installed on my rears when I replaced rotors/pads a couple of years ago.

I wonder when they changed to "front axle" for the helper springs. When I talked to Meritor 4 years ago they said all axles? I have helper springs on all four axles, cant see how it can hurt anything. As always DWMYFG.

I bet if you call back and talk to a different person, you'll get a different answer.

For those who may need the "Budd Alcoa wheels" which were used until 1997 or 1998, you may find them available at Pete's Tire in California. The manager told me at their booth during the Quartzsite RV show a couple years ago that they have Budd wheels which were removed to install the super wide Michelin rear 22.5 tires.

The PO on my coach had purchased the springs, but had been talked out of installing them by Wayne. I took them to MOT, had them installed on all four. I had a disk hang going between Silverton & Ouray, I'd put them on the steering wheel if I even suspected it MAY prevent a recurrence of that trip.
