First Gen 2000-2006 Toyota Tundra Brake Job: Front Discs, Rear Drums and Parts

By Core Brake Parts Tech Team — Circleville, OH warehouse

A first-generation (2000-2006) Toyota Tundra uses four-piston disc brakes up front and drum brakes at the rear, so a full brake job is really two different jobs: pads and rotors on the front axle, shoes and drums on the rear. The front wears out first because it does most of the stopping, and most owners replace front pads several times before the rear shoes are finished.

This guide walks through how the system works on this truck, the symptoms that tell you each axle is due, what to replace together, and what drives the cost of the job.

How the Brakes Work on a 2000-2006 Tundra

First-gen Tundras, 2WD and 4WD, left the factory with front disc brakes and rear drum brakes. Many owners later add rear disc conversions, which is why you will see both setups on used trucks. Look before you order parts: a drum is a closed round housing behind the wheel, while a disc conversion shows an exposed rotor and caliper.

• Front: a fixed caliper with four pistons, two on each side of a vented rotor. Because the caliper does not slide, the pistons do all the moving, and a sticky piston shows up as uneven pad wear.
• Rear: brake shoes inside a drum, pushed out by a wheel cylinder and pulled back by return springs, with a self-adjuster that keeps the shoes close to the drum as they wear. The parking brake works through the same rear shoes.
• Rear brake pressure: the rear circuit runs through a proportioning valve near the rear of the frame, which limits rear pressure so the drums do not lock ahead of the fronts. That valve and the lines around it matter on these trucks, as the recall section below explains.

Symptoms That Your Tundra Needs a Brake Job

Front axle

• Squeal that stops when you press the pedal: usually the pad wear indicator touching the rotor. The pads are near the end.
• Grinding: the friction material is gone and the steel backing plate is cutting the rotor. At this point the rotors are almost always scrap.
• Steering wheel shake under braking: uneven rotor thickness, a common complaint on heavy trucks that tow or brake hard from highway speed.
• Pull to one side: a sticking caliper piston or a collapsed hose. With four pistons per caliper, one seized piston can wear the inner and outer pads at very different rates.

Rear axle

• A pedal that sits lower, or a parking brake that pulls up further than it used to: the shoes are worn or the self-adjuster has stopped working.
• Pulsation felt in the seat rather than the steering wheel: an out-of-round rear drum.
• Wet residue on the inside of the tire or backing plate: a leaking wheel cylinder. Fluid ruins the shoe lining, so the shoes get replaced along with the cylinder.
• Scraping from the rear at low speed: a broken spring or shoes worn through the lining.

The Rust Recall That Touches the Rear Brakes

NHTSA campaign 09V444000 covers certain 2000-2003 Tundras originally sold in or registered in cold-weather, road-salt states. The rear cross member can corrode badly enough to let the spare tire separate and to affect the brake lines and proportioning valve, resulting in diminished braking capability. The remedy was an inspection of the cross member and related components, including the brake lines, with replacement where needed.

Even if your truck is a 2004-2006 or never lived in a salt state, treat this as a warning about that area. During a rear brake job, follow the steel lines from the frame to the rear axle and look at the proportioning valve and its bracket. Heavy scale, swelling or weeping at the fittings means the lines need attention before you trust the new shoes. You can check any VIN for open recalls on the NHTSA recall lookup.

The Front Brake Job: Pads, Rotors and What to Replace Together

The front job on a first-gen Tundra is straightforward, with a few habits specific to a four-piston fixed caliper:

1. The pads come out of the caliper once the retaining pins and anti-rattle clip are removed, so pads alone can be changed without unbolting the caliper.
2. To replace the rotor, the caliper has to come off the knuckle. Hang it with a caliper hanger or wire, never by the rubber hose.
3. Push the pistons back evenly with a spreader made for quad-piston calipers. Pushing one piston back can pop the opposite one out.
4. Clean the pad contact points, fit new pins and clips, and put brake grease only where the pad backing plate touches the caliper. Copper anti-seize on the rotor hub face helps the next job.
5. Tighten caliper bolts and lug nuts to the factory service manual values with a torque wrench, not an impact gun. Uneven lug torque is a common cause of rotor shake.

Replace together: pads on both sides of the axle, always. Rotors are worth replacing with the pads on a truck this age, because rotors that have been machined before are often near their minimum thickness, and new rotors bed in more evenly with new pads. If a caliper piston is seized or a dust boot is torn, replace the calipers in pairs. Browse brake pads, brake rotors and replacement brake calipers for this truck.

Choosing a pad: for commuting and light hauling, a ceramic stock-replacement pad is quiet and low-dust; see our ceramic brake pads. If you tow, run oversized tires or drive in the mountains, a truck-and-tow compound such as those in the Power Stop truck and tow line is built for the higher heat that glazes pads and distorts rotors on a loaded full-size pickup.

The Rear Drum Job: Shoes, Drums and Hardware

The rear job takes longer than the front because of the springs and adjuster, but it is manageable in a driveway with brake spring pliers and patience.

• Drum removal: back off the self-adjuster if the drum catches on the lip worn into it. Rust penetrant around the hub helps on trucks that have seen salt.
• Measure the drum: the maximum allowable diameter is cast or stamped on the drum. If it is over that, scored or out of round, replace it. Replace drums in pairs.
• Hardware: springs lose tension from years of heat cycles. A new brake hardware kit costs little and prevents the dragging and noise that tired springs cause.
• Wheel cylinders: peel back the rubber boots. Any fluid behind them means replace the cylinder now, not later.
• Adjust and test: set the shoes close to the drum, then follow the service manual procedure so the self-adjuster takes up the rest. Adjust the parking brake last.

Shop brake shoes for the rear axle. Work one side at a time so the untouched side shows you how the springs go back.

What Drives the Cost and How Hard the Job Is

The price of a Tundra brake job depends more on a few choices than on the truck itself:

• Pads only vs pads and rotors: pads alone is the cheapest job, but rotors on an older truck often need replacing anyway, and machining them at a shop adds labor.
• One axle vs both: most visits are front-only. Adding the rear drums, shoes and hardware roughly doubles the parts list and adds the most labor time because of the spring work.
• Extras found during the job: seized calipers, leaking wheel cylinders, rusted lines and a fluid flush all add to the bill, and rusty trucks tend to need more of them.
• Doing it yourself: labor is the largest share of a shop bill. The front job is a good first brake job for a home mechanic with a floor jack, jack stands and a torque wrench. The rear drums are moderate difficulty, mainly because of the springs.

If the pedal feels soft after the job, or the fluid in the reservoir is dark, bleed the system with fresh fluid of the type printed on the master cylinder reservoir cap. For everything else on the truck, start at our brake parts catalog.

Frequently Asked Questions

Does the 2000-2006 Toyota Tundra have rear disc or drum brakes?

Rear drum brakes from the factory, on both 2WD and 4WD trucks. If yours has rear rotors and calipers, a previous owner installed a disc conversion, and you need parts for that conversion instead of shoes and drums.

How many pistons are in the front calipers?

Four, in a fixed caliper, two on each side of the rotor. Use a spreader designed for multi-piston calipers when you push them back.

Can I replace the front pads without taking the caliper off?

Yes. The pads come out once the pins and clip are removed. The caliper only has to come off when you replace the rotor.

Should I replace the rotors with new pads?

On a truck this age it is usually the better choice. Old rotors are often thin or unevenly worn, and new pads bedded onto new rotors give the smoothest pedal and the fewest shake complaints.

Why does my Tundra shake when braking downhill with a trailer?

Heat. Towing and long descents build uneven pad deposits and thickness variation on the front rotors. New rotors plus a truck-and-tow pad compound designed for high heat address the cause, as does using a lower gear on long grades.

Is my Tundra covered by the rear cross member recall?

Campaign 09V444000 covers certain 2000-2003 Tundras sold or registered in specific road-salt states. Enter your VIN on the NHTSA recall lookup to see whether the work is open on your truck.
