1999-2007 Ford F350 Parking Brake Problems and Adjustment

By Core Brake Parts Tech Team — Circleville, OH warehouse

On a 1999-2007 Ford F-350 Super Duty, the parking brake is a small set of drum brake shoes that sits inside the hat of each rear disc rotor. When the pedal sinks too far, the truck rolls on a grade, or the rear wheels drag, the cause is almost always shoe adjustment, stretched or seized cables, or rust inside that little drum, and all three can be checked in an afternoon with basic tools.

How the F-350 Parking Brake Works

The Super Duty uses hydraulic disc brakes at all four corners for normal stopping. The parking brake is a separate, purely mechanical system. Behind each rear rotor, a pair of shoes is mounted to the backing plate, and the inside of the rotor's center section, the hat, is machined as a drum. This layout is called drum-in-hat, and Brake & Front End describes it as the most common parking brake design on vehicles with rear discs.

You apply it with the foot pedal under the left side of the dash. Ford's owner guide says to press the pedal down until it stops, and to release it by pulling the release lever. The pedal pulls a front cable back to an equalizer, which splits the pull between the left and right rear cables. Each rear cable works a lever and cam that spread the shoes against the drum surface inside the rotor.

Two things follow from this design. First, the shoes do not wear during normal driving, because they only touch the drum when the pedal is applied. Second, nothing adjusts them automatically every stop the way old rear drum service brakes adjusted themselves, so clearance is set by hand with the star wheel.

Symptoms and What Each One Points To

That last row matters. Ford's owner guide says the BRAKE warning lamp lights while the parking brake is set, and that if it stays lit after the brake is released it indicates low brake fluid and the system should be inspected right away. Do not assume a lit lamp is just the parking brake. The guide also notes a warning chime sounds if you drive more than 3 mph with the parking brake still set.

Common Causes on 1999-2007 Super Duty Trucks

Rust inside an unused drum

Plenty of automatic-transmission owners never touch the parking brake. Brake & Front End points out that when the parking brake is not used, rust and corrosion build up inside the drum. The shoes then ride on a rough, pitted surface, holding power drops, and the rotor can catch the shoes so hard it will not come off during a pad job. Using the parking brake regularly keeps the drum surface clean.

Cable stretch and seized cables

Cables stretch over the years, which adds slack and pedal travel. On trucks that live in salt states, water gets into the sheaths and the inner wire rusts in place, which can leave a wheel dragging after release. Brake & Front End warns that home remedies like spraying oil or solvent into a cable usually shorten its life by attracting grime. A cable that is seized or frayed gets replaced, not lubricated.

Worn equalizer and linkage

If pedal travel feels normal but the truck still rolls, look at the equalizer and pivots. Worn or rusted linkage that lets the pedal move without pulling the shoes tight is the classic sign of this failure.

Contaminated shoes

A leaking rear axle seal or a weeping caliper can soak the parking brake shoes. Oil-soaked linings will not grip no matter how well they are adjusted, and they have to be replaced after the leak is fixed.

Known recalls on early trucks

Two NHTSA recalls cover early Super Duty parking brakes. Recall 98V101000 covered 1999 Super Duty single rear wheel pickups whose parking brake, applied with 125 pounds of force on the pedal, might not hold the truck on a 20 degree grade; dealers burnished the parking brake to fix it. Recall 02V068000 covered 1999 F-250, F-350, F-450 and F-550 Super Duty trucks with manual transmissions, where the front parking brake cable input button could fail and let the truck roll; dealers replaced the front cable and the controller. If you own a 1999, run your VIN through the NHTSA recall lookup to see whether the work was done.

How to Adjust the Parking Brake Shoes

Adjust the shoes at the wheels before you touch cable tension. Tightening the cable to make up for loose shoes leaves the levers at a poor angle and the pedal still feels soft.

1. Chock the front wheels, release the parking brake, and raise the rear of the truck onto jack stands. Remove the rear wheels.
2. Find the rubber plug covering the adjuster access hole and remove it.
3. With a brake adjusting spoon or a thin flat screwdriver, turn the star wheel while you spin the rotor by hand. The Brake & Front End method is to turn it until the shoes drag on the drum, then back it off until the rotor turns freely. If the drag gets lighter as you turn, you are going the wrong way.
4. Repeat on the other side so both wheels are set the same way.
5. Apply and release the pedal several times to seat the cables, then confirm both rear wheels still spin freely with the pedal released.
6. Reinstall the plugs and wheels, torque the lug nuts to the value in the factory service manual, and test on a gentle grade with your foot ready on the service brake.

Brake & Front End stresses that you should never estimate a parking brake adjustment: either use the drag-and-back-off method or measure the drum and shoes with a brake gauge. Guessing leads to either a brake that will not hold or shoes that drag, heat the rotor and wear out early.

If the rotor is stuck on the shoes, back the star wheel off a few clicks through the access hole first. Hammering on a rotor that is still gripping the shoes can damage the parking brake hardware behind it.

What to Replace, and When to Do It Together

Pull the rear rotors and inspect the shoes and hardware whenever adjustment will not bring the holding power back. Replace the shoes as a set on both sides and fit a new hardware kit at the same time, because the small springs and hold-down clips lose tension and rust. Our brake hardware kits and brake shoe collection are the place to start.

The drum surface lives inside the rotor, so the rotor is part of the parking brake too. If the hat is deeply scored, has a rust lip, or is worn out of round, the parking brake will never hold properly on that rotor and new rotors are the fix. A rear rotor job is also the natural time to service the parking brake, because the rotor has to come off either way. For 1999-2004 F-350 dually 4WD trucks we carry the EBC GD7340 slotted rear rotor set, and our full range of brake rotors covers other configurations. If the rear pads are low while you are in there, the EBC Yellowstuff DP41779R rear pads fit 2005-2007 F-350 dual rear wheel 2WD trucks, and our brake pads collection covers the rest.

Replace any cable that is frayed, kinked, or will not slide back freely after release. On 1999 trucks with a manual transmission, check the front cable at the pedal assembly, the part addressed by the recall.

After new shoes or rotors, burnish the parking brake so the linings bed into the drum. Ford's own remedy for the 1999 recall was a burnishing procedure, which shows how much bedding affects holding power. Follow the procedure in the factory service manual rather than improvising one.

How Hard Is This Job?

An adjustment is an easy job for anyone who can safely raise a truck and pull the wheels. Shoe replacement is moderate: the rotors have to come off, which means removing the calipers and their brackets, and the small return springs are fiddly without a spring tool. Cable replacement ranges from easy for the rear cables to awkward for the front cable at the pedal. The Super Duty is heavy, so use jack stands rated for the truck and never work under it on a jack alone.

Ford's owner guide adds a practical point for towing and grades: press and hold the service brake, then set the parking brake, and chock the wheels if needed. It says a little movement as the brake takes the weight is normal, but if the parking brake cannot hold the truck it may need service or the truck may be overloaded.

Frequently Asked Questions

Does the F-350 Super Duty have rear drum brakes?

Not for normal stopping. The 1999-2007 Super Duty uses rear disc brakes. The only drum is the small parking brake drum machined inside the hat of each rear rotor.

Why does my parking brake pedal go almost to the floor?

Usually the parking brake shoes are adjusted too loose or the cables have stretched. Adjust the star wheels at both rear wheels first, then check the cables and equalizer if the pedal is still low.

Can I just tighten the parking brake cable instead of adjusting the shoes?

That is the wrong order. Set shoe clearance with the star wheel first. Pulling extra cable tension to make up for loose shoes leaves the pedal soft and can make the brake drag.

Why will my rear rotor not come off?

Rust inside the drum section of the rotor catches the parking brake shoes. Remove the access plug and back the star wheel off a few clicks, and the rotor should come off with light taps.

Should I replace the parking brake shoes when I replace rear rotors?

Inspect them every time. Replace them if the linings are thin, cracked, glazed or oil soaked, and always replace them in pairs with a new hardware kit.

What brake fluid does the 1999-2007 F-350 use?

Ford's Super Duty owner guide calls for DOT 3 brake fluid that meets Ford specification ESA-M6C25-A. The parking brake itself is mechanical and uses no fluid.
