Bob when I got our coach I drove to the tire shop and found the caliper dragging. Against the rules I spayed with cleaner lube . Beat with the tire sledge till it was loose and drove 1500 miles home. Had my son go out side first couple of stops to verify it was not dragging and checked temperature with heat gun regularly till I was comfortable with it. Once it was back in service it wasn't a issue. Got home cleaned and replaced brakes added helper springs. Still check after the first initial stop but has worked great since

So just got a chance to look at my parts today and notice that some things seem fairly big. I'm not sure if I ordered the right stuff now or not lol.
MERITOR KIT15016 - Meritor Genuine Air Disc Brake - Pin Slider And Return Kit X2

MERITOR KIT15006RH - Meritor Genuine Air Disc Brake - Shaft Replacement Kit

MERITOR KIT15007LH - Meritor Genuine Air Disc Brake - Shaft Replacement Kit

MERITOR KIT15625PM - Disc Brake Pad Set - Air Disc Brake, Fire/Emergency Trucks X2

MERITOR 3218K167 - Disc Brake Rotor - 15.3 in. Outside Diameter, U-Shaped Rotor

Just found out that I could stay another month here in Oklahoma City. So I think that I won't be getting this work done till late July. So I still have time if I need other parts. I'm not sure if the wheel seal is in one of these part bags. Or do I have to order one separate?

Appreciate craneman putting all of the pictures of his brake job online.

I did not see the helper springs for the slide pins. Did I miss them?

Don't see them on his list either.

John 44 I think that those springs are for the centering bolts.

Well you're right I didn't order them. I thought they were in one of the kits that I bought but evidently not. I'll order them tonight. Thanks for catching that! I do have three tubes of clay based grease. Now. One is mobile and the other two are meritor.
What about the axle seal? Anybody have a part number for that?
Thanks!

Okay I ordered the helper springs from meritor. Two sets didn't get me to $50 for free shipping so I bought another of the TriCore 26-in wiper blades That not only got me free shipping but I also from that large brake order got a $20 off coupon. So I have a few dollars extra to buy another six pack of Guinness.
Thanks for your help and as always I will post pictures and progress once it is done.

Almost had a cow for a second. Looks like there was only one spring in each package. Note to self look at the package closer. The springs are entwined together. So two packages of springs will get the rear done. I'm kicking myself a little bit that I didn't order four sets to do the fronts as well.
So now I have to think about that...

Okay an update and question. Arrived at John 44's place in Drummond Tennessee today. Going to start work in the morning. Got 5 days of rain coming so it's going to be fun.
My question is should I block the coach up? Meaning raise it all the way up and put in the stands?
Still need to rebuild my front six pack so I have a little bit of a leak. I'm wondering if it is better to raise or leave it down?
Thanks!
Of course! They'll be plenty of pictures hopefully. If it doesn't stay at 106° for the rest of the week, maybe I will survive this.
Appreciate everybody's input on the thread. Really appreciate John 44 and his wife and family letting me hang out here until it's done.

I block mine up anytime I'm working near or under the coach. Way to easy to be safe.

Re: New tires and other surprises

My recommendation is to block it up. It gives more room to work on the brakes and if you need to any other work such as your 6 pack it is necessary.

Thanks gentlemen. I do have a leak in my front six pack and a rebuild kit and if I have chance to do it while I'm here I'm going to do that too. Raising and blocking my front driver's Side wheel is always an issue though but I will give it a try. Which is of course why I need to rebuild the six pack lol.
It's supposed to rain The next few days starting tomorrow and it's still going to be in the high '90s.
Got to love it!

You can use a bottle jack to finish raising the driver's side wheel. John will help you position it.

Okay got the wheels off. That was an adventure when they changed the tires. Of course they used in the matic impact driver and I'm sure they over torqued it. David and I got it off with two breaker bars. My first one 3/4-in drive breaker bar broke on one of the nuts. Fortunately David had another one. We use two tubing extensions on top of the bar so it was probably a good 6 ft. Long and that was able to break the nuts. Finally, That was hard. Was jacking and getting the 25 ton jack stands position properly That took a little doing. But it's done. Next up is removing the caliper.
I know how to remove the caliper I believe, but one thing I'm not sure about is removing the spring brake from that side. I've never done that so I know there's like a rubber gasket. You pull that up and then you pulling something. Maybe push down something. I don't know. The videos that I saw weren't real clear on that one. Any ideas?
The next issue is pulling and separating the ventilated disc from the axle. We're going to attempt that next after a hydration and cooling break. We started at 7:30 and by 10:30. I'm already exhausted. I probably just sweated about a gallon and I've only put in about 2 l of water. We're two old guys trying to do this so it takes time.
The other interesting thing was my crossfire system wasn't exactly sure how to remove that and so I just did. And of course both tires. Deflated That made it a little bit harder to get the tires off the studs, but we eventually did get that done too.

Dude! Nice Rotor!

Block the house in its full up position. Don't even think about if it's necessary or not, just do it.

Jacks stands to support the axle: Check.

Lug nuts. I bring my own torque wrench and insist on doing the final tightening either myself of with my close supervision. End of story.. Over tightening the nuts brings you that much closer to failure. It's like Goldilocks and the 3 bears.

Cage the spring in the rear cans before removal. Look it up, study the picture and make sure the caging bolt is secure. If the one on the outside of your can is missing, hit the truck supply NAPA.

You wrote "You pull that up and then you pulling something. Maybe push down something. I don't know. The videos that I saw weren't real clear on that one. Any ideas?"

Yeah, look at the parts manual and the exploded view.

The good news about all of this is that you can take your time, you don't have to worry about the patient being alive at the end of the procedure.

When I got the snow tires for the Monaco I saw them with a torque wrench so I though great
until I wanted to put the summer tires on. If they over torque the nuts the torque wrench is
useless. My son figured that 2 of the nuts were over 1000 ft. lbs.

Mariner's Choice's Never Seez reduces the torque by 41%, the most reduction of any no seize product. You only need a 300# torque wrench to equal the recommended torque for the Budd style nuts. Never Seize Mariner's Choice Anti-Seize

About one turn with the torque ratchet and then my tiny Makita 18V 1/4" impact spins them off (or on). That's all I use.

If worried, you can purchase the loose nut indicators (38mm for Budd) at: loose wheel nut indicators 38mm: Search Result | eBay

"Cage the springs before removal." BUT it is much easier if you release the parking brakes before you cage. They are almost to the fully caged position with parking brake released IE air in spring brake. Then set the parking brake to release air from spring brake after being caged. You can do by skipping this step but you will have to wrench them the entire distance against the spring.

They sell all sizes at the link I provided. I was using ours as an example. Just measure the nut and compare.

Thanks Scott. Unfortunately I was outside all day working after I posted that last post so didn't see this until tonight. I spoke to Chuck IE craneman today and he gave me some good advice on some of the issues I'm having. I was able to cage to breaks after watching a YouTube video so no issues there. The next issue that we had was getting the caliper pins off. The top wasn't so bad. The bottom was quite difficult. Once we got the pin out, saw that it had some deep corrosion in a few spots. I don't think that this issue is just with the slide pin so I may be wrong, But I did buy the rebuild kits on the calipers because the company in Oklahoma City wanted to put new calipers on. I figured rebuilding them would be better. Anyway, now I'm at the point where I've got the caliper off and the can separated from it and I am trying to get the piston out of the bore. The manual calls for a special tool that I don't have so I called craneman. He had some good ideas. I'm going to give that a shot tomorrow. If my ideal doesn't work which is to use some 8-in c clamps, I may have to grind them down a little bit to get at the snap ring that's holding the piston in. If the c clamps don't work then I will try something different that craneman had mentioned. I went to harbor freight this evening to get to see clamps and I found a tool to compress a disc brake on a car. It won't really work for this application, but it has a nice piece of metal that I can bend and use it to compress the piston. It shouldn't take very much compression to release the c-clamp. Going to do that in the morning. The other thing I'm going to do tomorrow is to pull the axle so we can replace the disc rotor. If I can get the caliper rebuilt tomorrow and I have a seal for the axle. I'm hoping by this time tomorrow the passenger side wheel will be done. Then it's on to the driver's rear wheel where I'm going to pull the wheels and check the caliper. The company in Oklahoma City that looked at my code said that that caliper was not moving yet. I had really no issues with stopping and breaking the coach on my way from Oklahoma to Tennessee. I don't know if I completely trust what they told me.
