Question about 2007 Ford E-350 Super Duty Length XLT
Sunday May 24 2009
I have a 1989 E350 with a 7.3 liter Navistar engine.
Since it was new on steep grades the brake pedal fades to the floor. Allowing the brakes to cool remedies the problem.

"Your question is getting a little dated but I just ran across it today. Have been there and done that with my 89 E350 MH. This issue was covered about 2 weeks ago and I'm surprised no one remembered the discussion...
"At the root of your problem is fact that your rig came with aluminum pistons in the front calipers. They are GREAT for transfering heat from pads to brake fluid and the piston is in direct contact with both. Ford has had a TSB for a number of years describing this problem and the fix. You need to rebuild the calipers and replace the aluminum pistons with the phenolic replacements..."
Can you point me to the discussion postings around the beginning of 2008 which Mickey says are about those aluminum pistons in those calipers, and the brake pedal fade?
Please, is there a way you may contact Mickey to give me more information as to if my particular E350 has these aluminum pistons in the calipers? Which engine does Mickey have in his E350?
If it turns out my E350 has these aluminum pistons in the calipers which is the most economical way of repair?
How can I find out if my E350 has these aluminum pistons in the front brake calipers?
At my E350's age a front brake caliper replacement is not out of the question: Are brand new calipers a better choice than rebuilt? If so, which brands of brand new front brake calipers are best, and do any of these have aluminum pistons in these front brake calipers? Which ones have the phenolic pistons (in these brands of brand new front brake calipers)?
Please, I'm wanting to find the TSB 98-5A-13, TSB 98-5A-38, and a copy of Ford recall 92S44, which may be pertinent to my 1989 E350's front brake calipers, heat transfer, and brake pedal fade.
(Luckily I"ve found TSB 98-5A-29, which is of some use for this E350 problem, if my E350 has it)...
I assume I'll be using Motorcraft super duty BRSD450 brake pads for my E350.
Is there any standard procedure to follow for sudden brake pedal fade?
By brake fluid reservoir cap is part number FO3Z2162A. (The O in this part number is a letter O, not a number Zero.Please, can you locate this new brake fluid reservoir cap? The rubber gasket in my brake fluid reservoir cap may be old.
When my E350 was brand new, the original owner had the rear axle gearing rebuilt; this allows great fuel mileage but my van isn't held back so well down grades by the gearing inside the rear axle...I'll call the original owner to try to find out which gearing is now inside the rear axle.
My VIN: 1FTHS34M1KHC35975. My E350 has the extended body type.
First, if the recall applies to your van, it can be done anytime. There is no time limit on recalls. Call your dealer with your 17 Digit VIN number and they can check. Please rate as solved if this is what you need. thanks.
Here is the recall:
Safety Recall 92S44 - Certain 1988-1991 F250/350 Trucks for Loss of Front Brake Effectiveness
Certain 1988-1991 F250/350 trucks over 8500 lb GVW with 7.5L EFI or 7.3L diesel (4x2 and 4x4) and 5.8L EFI (4x4 only). Trucks under 8500 lb GVW. 5.8L EFI (4x2) and F-Super Duty light trucks are not involved in this recall. Specific vehicle information is as follows:
AFFECTED VEHICLES ASSEMBLY PLANT PRODUCTION DATES F250/350 Norfolk Job#1 1988 to 4/18/91 Kansas City Job#1 1988 to 4/25/91 Ont. Truck Job#1 1988 to 5/1/91 Mich. Truck Job#1 1988 to 5/11/91 Twin Cities Job#1 1988 to 5/29/91
Reasons For Recall
In certain extremely severe driving conditions, the vehicle may experience a loss of front brake effectiveness due to overheating of brake fluid. These vehicles have a split brake system and the rear brakes remain operational. This condition has been reported primarily in vehicles operated in mountainous regions, and on vehicles that have been in service for a minimum of one to two years and where the brake fluid has absorbed moisture from the air, lowering its boiling point. It usually involves heavily loaded vehicles driving on long, steep grades, or when towing at, or near, the Maximum Gross Combination Weight Rating (GCWR) for towing. Warm weather also appears to contribute to this condition. To correct this condition, dealers will install insulators in the front brake caliper pistons on all the affected trucks. 7.5L EFI engine equipped trucks will also have insulation installed on selected portions of the front brake lines.
PART NUMBER DESCRIPTION CLASS DEALER PRICE F2TZ-2C361-A Kit-Brake Caliper Piston Insulator (All Except 7.5L Engines) BG F2TZ-2C361-B Kit-Brake Tube Insulator Jacket (Required Only For Vehicles Equipped With 7.5L EFI Engines) Kit Also Includes Brake Caliper Piston Insulators

If the pistons are aluminum, continue as described below.
Do not bend the tabs. The inner edge of the washer may crease slightly as it passes over the barb. This is permissible provided that the crease can be smoothed out once the washer is in place. The washer must be installed without tearing.
