2001-2011 Ford Ranger Front vs Rear Brakes: What Wears First and What to Replace

By Core Brake Parts Tech Team — Circleville, OH warehouse

On a 2001-2011 Ford Ranger, the front brakes almost always wear out first. The front disc pads and rotors do most of the stopping on every pull-up, while the rear drum shoes carry a lighter share and can last through two or more front pad jobs. The catch is that the rear drums fail in quieter ways - a seized self-adjuster, a leaking wheel cylinder or a stuck parking brake - so they still need a look every time the fronts come apart.

How the Ranger's brakes are split front to rear

This generation of Ranger uses disc brakes up front and drum brakes at the rear on most trucks. The front of each wheel carries a rotor squeezed by a caliper and a pair of pads. The rear hides a pair of shoes inside a cast drum, pushed outward by a wheel cylinder, with a star-wheel self-adjuster and a cable-operated parking brake built into the same assembly. Ford's own recall filing for 2010 Rangers refers to the parking brake shoes and the right rear actuator, which is the drum-style rear setup most owners are working on.

Ford's 2011 Ranger owner's manual covers a four-wheel anti-lock brake system with an ABS warning lamp. None of that changes which end wears first; it just means a warning light on the dash is worth reading before you order parts.

Why the front does most of the work

When any truck slows down, its weight pitches forward onto the front tires. More weight on the front tires means more grip there, so the brake system is designed to send more stopping force to the front axle. On a pickup like the Ranger this effect is even stronger when the bed is empty, because the rear end is light. The result is simple: the front pads turn more energy into heat on every stop, and they wear faster. The rear drums are sized for their lighter job and see far less heat.

Symptoms: which end is telling you something

Ford's 2011 Ranger owner's manual notes that occasional brake noise is normal, but a metal-to-metal sound, a continuous grinding or a continuous squeal means the linings may be worn out and should be inspected. It also flags a continuous vibration or shudder in the steering wheel while braking as a reason for inspection. Here is how to sort those out by axle:

• Squeal or grind from the front wheels: Front pads worn to the wear indicator or to the backing plate. If it is grinding, plan on rotors too.
• Steering-wheel shake when braking: Almost always the front rotors - uneven thickness or pad material deposits. Rear drums that are out of round are more likely to pulse through the pedal and the seat than the wheel.
• Pedal sinks lower than it used to, but firms up after a pump: Classic rear drum symptom. When the self-adjusters stop working, the shoes sit farther from the drum and the pedal has to travel further before the rears engage.
• Parking brake handle or pedal goes almost to the floor: Rear shoes out of adjustment, a stretched cable, or a disconnected cable at the rear actuator.
• Wet or oily inside of a rear tire: Leaking wheel cylinder or axle seal. Fluid on the shoes ruins them and must be fixed before new shoes go in.
• Pulling to one side: Usually a front caliper sticking or a collapsed front hose, but a contaminated rear shoe can cause it too.

The manual also points out that pedal pulsation with noise under panic stops or on loose gravel, bumps, wet or snowy roads is normal ABS operation. If the ABS lamp stays on or flashes, the ABS may be disabled, though normal braking still works. If the red BRAKE lamp is on with the parking brake released, Ford says to have the brake system serviced immediately.

Checking both axles the right way

Front disc brakes

With the wheels off, look at the outer pad through the caliper and at the inner pad from behind. Compare the thickness to the new pad you plan to buy, and look for uneven wear between inner and outer pads, which points to seized caliper slide pins. Run a fingernail across the rotor face: a deep lip at the outer edge, heavy grooves, blue heat spots or cracks mean the rotor should be replaced rather than reused.

Rear drum brakes

Pull a drum and check the shoe lining thickness, then look at the wheel cylinder boots - peel one back slightly and any fluid behind it means the cylinder is leaking. Spin the star-wheel adjuster by hand; it should turn freely. The Know Your Parts technical article on drum self-adjusters explains that on this type of brake the adjustment happens when the brakes are applied while backing up or when the parking brake is set, and that a groove worn into the adjuster lever or worn teeth on the notched wheel can stop the adjuster from working, leading to poor pedal height and poor brake balance. Look inside the drum for a heavy ridge at the outer edge and for scoring.

Check fluid level too. Ford's manual notes that the fluid level drops slowly as the brakes wear and rises when new parts are installed, and that a level between MIN and MAX needs no topping off. A level below MIN is a reason to look for a leak, not just add fluid.

What to replace at the same time

Front axle

• Pads, both sides: Always as an axle set. Browse brake pads for Ford trucks or step up to low-dust ceramic brake pads for daily driving.
• Rotors: Replace them if they are grooved, heat-checked or causing shake. Fresh front brake rotors let new pads bed in evenly and are usually cheaper in time than machining old ones.
• Hardware: Abutment clips and slide pin boots. A brake hardware kit costs little and prevents the rattles and uneven wear that shorten pad life.
• Calipers: Only if a piston is stuck, a boot is torn or a slide is seized. See replacement brake calipers.

Rear axle

• Shoes, both sides: As an axle set from rear brake shoes.
• Spring and adjuster hardware: Return springs weaken with heat, and adjuster parts wear. The Know Your Parts article notes that replacing the adjusters helps ensure proper brake application and pedal height, and that adjusters are most active in the first stretch of driving while new shoes seat in. Replacing the springs and adjuster parts with the shoes is cheap insurance.
• Wheel cylinders: Replace any that are wet or have stuck pistons. Many techs replace them with the shoes on an older truck because a leak afterward ruins the new linings.
• Drums: Replace if scored, cracked or worn past the maximum diameter cast into the drum.

A parking brake recall worth checking on 2010 models

NHTSA campaign 10V202000 (Ford recall 10S12) covers certain 2010 Rangers with a manual transmission built from June 8, 2009 through February 2, 2010. According to the recall summary, the parking brake cable can disconnect from the right rear actuator in cold weather if wet parking brake shoes freeze in the applied position and the brake is then released. The pedal then has extended travel and may not fully apply the parking brake. The remedy is a revised right rear parking brake actuator installed by a dealer at no charge. If you own a truck in that range and are doing rear brakes, run the VIN through NHTSA's recall lookup first.

How hard is the job?

Front pads and rotors on a Ranger are a solid first brake job for a home mechanic with a jack, stands, basic sockets and a caliper piston tool. Rear drums take more patience: the springs are strong, the parts must go back in the right order, and the self-adjuster must be installed on the correct side so it tightens rather than loosens. Take a photo of one side before you start and do one side at a time so the other stays assembled as a reference. Tighten caliper bolts and lug nuts to the values in the factory service manual, pre-adjust the shoes so the drum just drags, and then set the adjusters by making several stops in reverse. Bed in new front pads with a series of moderate stops before any hard braking.

Frequently Asked Questions

Should I replace front and rear brakes on my Ranger at the same time?

Only if both are worn. The fronts usually wear first, and there is no benefit to throwing away rear shoes with plenty of lining left. Do inspect the rears every time you do the fronts, because adjuster and wheel cylinder problems are easy to miss.

Why does my Ranger's brake pedal feel low after a front pad job?

The caliper pistons were pushed back, so pump the pedal several times before driving. If the pedal is still low, the rear shoes are probably out of adjustment. Make several stops in reverse, and if that does not help, pull the drums and check the self-adjusters.

Can I switch my Ranger to rear disc brakes?

Conversions exist, but they involve the axle, parking brake and hydraulic balance of the whole system. For a daily driver or work truck, healthy drums with fresh hardware stop the truck as designed.

What brake fluid does a Ranger use?

Use only a fluid that meets the Ford specification listed in the maintenance specifications section of your owner's manual. Do not mix in a different type, and flush the old fluid if it is dark.

Is steering-wheel shake the front or rear brakes?

Almost always the front rotors. Replace them in pairs with new pads, and clean the hub face of rust so the new rotors sit flat.

How often should I check the rear drums?

Every time the wheels come off for front brake or tire service. It takes a few minutes to pull a drum and look for leaks, lining thickness and a free-turning adjuster.
