Strange Shifting, now only goes in reverse.

you could try replacing the pistons on the transmission as they are ceramic in nature and they break apart and it and the pin fall into the pan. Try or for transmission piston kits. If that doesnt work they also have transmission rebuild kits.

Installing rear brake caliper rebuild kit.

To remove piston safely use the brake pedal to press out piston. You will need to remove the pads so it can do this. You will need a container to catch the fluid when the piston comes out. Clean the the piston with a fine polishing cloth 600 grit or higher so as not to leave scratches, replace piston if it pitted or burred. Clean inside of caliper, remove inside seal with dental type tool. Roll in the new seal, position same as old one. install new outter dust boot if equipped with one. Lubricate seal and leading edge of piston with brake fluid. Slide piston into calipier. You will need to make sure it is started straight and then use a C-clamp to compress the piston all the way in. Never ever use any oils or grease any any internal brake parts because it will cause seal failure. Clean parts are critical, but again , no petroleum products. Good luck

Help-Ford E-350 Brake problem

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
Affected Vehicles
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

Brake Caliper Piston Insulator Kit
Installation Instructions
  1. Remove the front wheel and tire assemblies.
  2. Remove the brake calipers from the rotors. Refer to the appropriate shop manual for the procedures.
  3. Remove the inner and outer brake linings.
  4. Inspect the brake caliper pistons. If the pistons are phenolic, (brown in color) no modifications are required. Reassemble the calipers as described in the shop manual. If the truck is equipped with a 7.5L EFI engine, install the brake tube insulator kit. If the truck is not equipped with an 7.5L EFI engine, install the wheels and tires and release the truck.
    If the pistons are aluminum, continue as described below.
  5. Remove the steel retainer and Nomex thermal washers from the kit.
  6. Place a steel retainer on a bench with the tabs facing up. Refer to Figure 1.
  7. Place a Nomex thermal washer over the tabs so that it rests on the barb of each tab. Then, carefully press it over the barb of one of the tabs. Repeat the procedure for each of the remaining tabs.

    • NOTE:
      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.

  8. Push the washer down onto the back face of the retainer. Be sure it is seated uniformly on the retainer. Once installed, do not use an adhesive or other aid to hold it in place. This is neither necessary nor permissible.
  9. Snap an assembled insulator into the inside diameter of each caliper piston. Be sure the assembly is firmly seated on the rim of the piston. See Figure 2.
  10. Install the inner and outer brake linings.
  11. Clean the caliper slide surfaces on the caliper and the spindle with a wire brush and lubricate with Disc Brake Caliper Slide Grease, D7AZ-19590-A (ESA-M1C172-A) or equivalent.
  12. Reinstall the brake calipers. Refer to the appropriate shop manual for the procedures.
  13. Install the wheel and tire assemblies.

Water in oil

Dear akwelectrica,
When a full kit was installed....WHAT was installed??? Were the OIl seals replaced?? Were the Low Pessure Seals Replaced?? Were the high Pressure Seals Replaced?? Was the OIL changed?? If the oil was changed...did all water in the oil compartment been removed?? Also did the suction and delivery valves were replaced?? Now if all these things were done, BUT the pistons were not changed, than the whole kit was done for nothing!! My suspicion is that the PISTONS were not changed. But if all the kit was used and even the PISTONS were changed, than you must for sure have a cracked or damaged head. When I say the HEAD...I am always refering to the part that holds the pistons. But in rare circumstances even the outer head could be damaged. Ask your "Service Tech" what he replaced and you will know the answear. As I said..I suspect that the PISTONS were not replaced by New Ones.
