Front rotors on E450 Chassis

I've had brake hoses that I know for a fact were never abused (drum brakes) collapse inside and not allow brake fluid thru. Fairly young 1970 Mustang. Disconnected the line, you could stand on the brake pedal and nothing would come out. Removed line, all kinds of fluid came out of hard tube. It happens.

Thanks for all the great information. As soon as the weather cools down a bit I plan to take a close look at the brakes and go from there. I will probably re-visit this site and have more questions.

Sounds to me like the mechanic may have mistreated your brake hoses during the brake work. How?

Or, putting vice grips on the brake hose.

I FF'd through that linked YouTube. Now THAT E450 NEEDED a Brake Job. Notice it's a Box Truck. Far worse abuse than we give our RV's.

Note on the Calipers mounted upside down, bleeder down not up. Our new brakes, from a 2012 E450, have bleeders on both ends of the calipers. The Pads have to go in just right, but the Calipers now mount to either side. VERY WISE on Ford's part. Only one part number now. Still different Hoses though, for Right and Left.

You may not have heard this, but starting in 2008, every E150, E250 and single wheel E350 uses the same Brakes and Axles. Actually the E450 and DRW E350 do too. The Hubs and therefore Rotor Assemblies differ according to single or dual wheels. Different springs are used according to weight ratings, but the axles and spindles are all the same.

Well, every manual tells us to support the Caliper by tying it up, using wire or cord. Common sense tells us not to twist the hose while removing, tying or reinstalling the Caliper. How many are that careful, and how many "stick it someplace." Then it falls, weight of the caliper jerking the hose and straining the connector crimps?

Friend was having front end work done at one of the big tire company stores. Firestone, Goodyear, I forget with. A BRAKE HOSE was supporting the disassembled suspension, against coil spring pressure. Stretched tight as a bow string.

Assuming you have dual rear wheels, the front rotor looks like this

Might as well do it right and replace the caliper and pads.

I second the comment of replacing the brake hose.

I'll just add that while you are in there replacing the calipers and rotors etc, REPLACE the front brake lines.

E450 known problem with them collapsing on the 'inside'. You won't see any damage on the outside.

Been there done that, put new brakes on did not replace brake lines. Mechanic said the looked fine. :R

It's not an issue of the vehicle mileage, but the age of the vehicle.
An RV that sits up probably will need calipers and a brake fluid flush.

My calipers would stick in traffic. Causing the pads to over heat and crystallize.
I ended up putting slotted rotors and new calipers that have metal pistons. No issues now.

I agree that the mileage should not be a problem, although I have driven quite a few miles in a the northeast Georgia mountains. I mainly want to visually check everything because I don't have a shelter and it is always exposed to the elements. At the very least I figure the caliper pins need lubricating to keep them operating without sticking due to rust etc.

One of our OP's documented an E450 brake job and I want to say he was out around 80,000 miles.

At 19,000 I doubt it needs anything on brakes. Let along ball joints etc.

By pulling the wheels, you should be able to see enough of the Pads to determine the thickness and that they're worn evenly to the thicknesses you can see. And you can see if the rotor surfaces are blued from overheating, or scored from trapped pebbles, etc.

I wouldn't even pull the rotors if they look OK. Cope with Caliper Brackets some other day.

If anything goes wrong with the brakes at this coach's age and mileage, it'll be stuck calipers or collapsed hoses.

Calipers DO NOT always stick on the slides, as often mentioned. The pistons can also get sticky and not allow the brakes to release. That happened to me on our E450 several years ago at about 30,000 miles. It hadn't had much use for a couple years before we bought it.
