# Drum Brake Shoe Replacement and Adjustment DIY 1998 Toyota Tercel

If you're noticing a decline in your 1998 Toyota Tercel's rear braking performance, hearing unusual noises, or experiencing a spongy brake pedal, it might be time for a Drum Brake Shoe Replacement and Adjustment DIY. The rear drum brakes on your Tercel are crucial for balanced stopping power and parking brake function. Addressing worn shoes promptly can prevent more extensive damage, improve overall vehicle safety, and restore confidence in your car's stopping ability. This comprehensive guide will walk you through the process, focusing on the specific needs of your 1998 Tercel, ensuring you can tackle this common maintenance task effectively.

## What drivers notice on this 1998 Toyota Tercel

Owners of a 1998 Toyota Tercel often first notice issues with their rear drum brakes through changes in how the car feels when stopping. Unlike front disc brakes, which handle most of the primary stopping force, rear drums contribute significantly to overall braking stability, especially during panic stops, and are absolutely essential for the parking brake's functionality. When the shoes begin to wear out, or the adjustment becomes loose, the symptoms can range from subtle, like a slightly higher parking brake lever, to quite alarming, such as reduced stopping power or unusual noises, impacting your confidence in the vehicle's stopping ability. Early detection and intervention are key to maintaining your Tercel's safety and performance.

## Symptoms and warning signs

Recognizing the early signs of worn drum brake shoes can save you time and money, preventing further damage to your braking system and ensuring your 1998 Toyota Tercel remains safe. Keep an eye out for these common indicators:

*   **Reduced rear braking effectiveness:** The car may feel like it takes longer to stop, or the rear end might not feel as planted during braking, especially under moderate to heavy pedal pressure.
*   **Grinding, squealing, or scraping noises from the rear wheels:** This often indicates metal-on-metal contact, meaning the brake shoe material is severely worn down to the metal backing plate, or foreign debris is trapped within the drum.
*   **Excessive brake pedal travel or a "spongy" pedal feel:** If the shoes are too far from the drum, the pedal will need to travel further to engage them, leading to a soft or low pedal that requires more effort to achieve braking.
*   **Vehicle pulling to one side under braking:** While more common with front brake issues, uneven wear, a seized wheel cylinder, or a stuck adjuster on one rear wheel can cause a slight, but noticeable, pull.
*   **Parking brake not holding as effectively:** If the parking brake lever pulls up much higher than usual (e.g., more than 5-7 clicks), or the car rolls on a slight incline with the parking brake engaged, the shoes may be worn or out of adjustment.
*   **Vibration during braking:** Warped drums, unevenly worn shoes, or a malfunctioning automatic adjuster can sometimes cause a subtle vibration felt through the chassis or brake pedal.
*   **Burning smell:** A distinct burning odor, especially after heavy braking, can indicate overheated shoes or excessive friction, often due to dragging shoes or improper adjustment.

## How to verify and confirm the issue

Before diving into a repair, it's important to confirm that your drum brake shoes are indeed the source of the problem. Here’s how you can verify the issue on your 1998 Toyota Tercel:

*   **Visual Inspection:** This is the most direct method. Safely jack up the rear of your Tercel and support it securely on jack stands. Remove the rear wheels. Carefully remove the brake drum (it may require persuasion with a hammer if rusted). Once the drum is off, visually inspect the brake shoe lining thickness. If the lining is less than 1/16th of an inch (about 1.5mm) thick, or if you see rivets, the shoes need replacement. Also, check for signs of brake fluid leaks from the wheel cylinder, which would contaminate the shoes and require additional repair. Inspect the drum for deep grooves, scoring, or excessive wear.
*   **Brake Pedal Test:** With the engine off, pump the brake pedal several times until it becomes firm. Then, apply steady pressure. If the pedal slowly sinks to the floor, it could indicate a master cylinder issue or a leak elsewhere in the hydraulic system. If it remains firm but feels low, it strongly suggests the shoes might be out of adjustment or worn.
*   **Road Test (Safe Area):** In a quiet, safe area, perform several stops from moderate speeds (e.g., 20-30 mph). Pay close attention to any noises, pulling, or changes in pedal feel. Light braking can sometimes highlight squeals, while harder braking might reveal grinding or a noticeable decrease in rear-end stability.
*   **Parking Brake Test:** On a very slight incline, engage the parking brake fully. If the vehicle still rolls, or if the parking brake lever pulls up excessively high (more than 5-7 clicks), it's a strong indicator of worn shoes or an out-of-adjustment system. This test specifically targets the rear drum brakes.

## Common causes (most likely first)

Understanding why your drum brake shoes wear out can help in preventing premature failure in the future and identifying other potential issues:

*   **Normal wear and tear:** This is by far the most common cause. Brake shoes are friction material designed to wear down over time with use. Their lifespan depends heavily on driving habits and conditions.
*   **Contamination:** Oil, grease, or brake fluid leaks from a faulty wheel cylinder can saturate the brake shoe material, drastically reducing its friction capability and causing poor braking or grabbing. This contamination renders the shoes ineffective and requires replacement of the shoes and the source of the leak.
*   **Overheating:** Prolonged or heavy braking, especially when descending long grades or towing, can cause the shoes and drums to overheat. This leads to glazing of the shoe material, which reduces friction and can cause a hard pedal feel and reduced stopping power.
*   **Corrosion or rust:** If the vehicle sits for long periods, or in humid environments, rust can build up on the drum and backing plate, hindering shoe movement and causing uneven wear or sticking.
*   **Faulty automatic adjusters:** The star wheel adjuster mechanism inside the drum assembly is designed to keep the shoes properly spaced from the drum as they wear. If this mechanism seizes, breaks, or is installed incorrectly, the shoes won't adjust, leading to excessive pedal travel and reduced efficiency.
*   **Worn or damaged return springs:** Weak or broken return springs can cause the brake shoes to drag against the drum, leading to premature wear and overheating.

## Step-by-step diagnosis and fixes

Replacing and adjusting drum brake shoes on your 1998 Toyota Tercel is a manageable DIY task, but requires patience, attention to detail, and the right tools. Always refer to a service manual for specific torque specifications and safety procedures. For more general repair guidance, explore our all repair guides.

1.  **Safety First:** Park your Tercel on a level, firm surface, engage the parking brake, and chock the front wheels. Loosen the rear lug nuts slightly, then jack up the rear of the vehicle and support it securely on jack stands. Remove the rear wheels. Safety glasses and gloves are recommended.
2.  **Remove the Brake Drum:** The drum may be stuck due to rust fusing it to the hub or a lip worn into the inner edge. Use a rubber mallet to tap around the drum's perimeter. If it's still stubborn, there might be two threaded holes (typically M8x1.25) on the drum face; thread two bolts into these holes and tighten them alternately to push the drum off the hub. If the drum won't come off, the shoes might be adjusted too tightly; you may need to access the star wheel adjuster through a small hole in the backing plate (or the drum itself) to retract the shoes slightly. Consult your vehicle's service manual for the exact location of this access hole.
3.  **Inspect Components:** With the drum off, thoroughly inspect the condition of the existing shoes, springs, wheel cylinder for leaks (a wet, oily residue indicates a leak), and the drum's inner surface. Take detailed photos of the assembly before disassembly – this is invaluable for correct reassembly. Note the orientation of the shoes, especially the primary (shorter) and secondary (longer) shoes, and all springs.
4.  **Remove Old Shoes and Hardware:** Using brake spring pliers or a pair of needle-nose pliers, carefully remove the return springs, hold-down springs and pins, and the adjuster mechanism. Pay close attention to how everything is assembled. It's often easiest to remove the bottom spring first, then the hold-down pins, and finally the upper return springs. Be cautious as springs can snap back forcefully.
5.  **Clean the Backing Plate:** Thoroughly clean the backing plate with brake cleaner and a wire brush to remove all dust and debris. Apply a thin layer of high-temperature brake grease (silicone-based, specifically designed for brakes) to the contact points where the brake shoes slide against the backing plate. Avoid getting grease on the shoe lining or drum surface.
6.  **Install New Hardware and Shoes:** Install the new hardware kit (springs, pins, adjusters) that typically comes with new shoes. Reassemble the shoes onto the backing plate, meticulously following your reference photos. Ensure the automatic adjuster (star wheel) is installed correctly and moves freely. On most Tercels, the longer shoe (secondary shoe) usually goes towards the rear of the vehicle, and the shorter (primary) shoe towards the front.
7.  **Install the Drum:** Before installing the drum, ensure the star wheel adjuster is wound in almost completely, making the shoes as retracted as possible. This will allow the drum to slide on easily. If the drum has a significant lip, deep grooves, or is out of round, it should be resurfaced by a machine shop or replaced to ensure optimal braking performance. You can find replacement parts for your 1998 Toyota Tercel by browsing our [vehicles](/vehicles) section.
8.  **Initial Adjustment:** Once the drum is on, you'll need to adjust the shoes. Access the star wheel adjuster through the small hole in the backing plate (usually covered by a rubber plug). Using a brake spoon or a flathead screwdriver, turn the star wheel until the drum feels snug, with a slight drag when you rotate it by hand. Then back off the adjuster 3-5 clicks until the wheel spins freely with minimal drag. This provides a good starting point for the automatic adjusters.
9.  **Final Adjustment (Brake Pedal Method):** With both wheels on, lower the vehicle. Start the engine and pump the brake pedal firmly 20-30 times. This allows the automatic adjusters to take up any remaining slack, ensuring the shoes are properly positioned against the drums. The pedal should feel firm and consistent. Alternatively, you can perform a series of slow, controlled stops in reverse, which also helps activate the adjusters and seat the shoes.
10. **Parking Brake Adjustment:** After the main shoes are adjusted, check the parking brake. If it still feels loose or engages too high, you may need to adjust the cable at the parking brake lever inside the cabin. Typically, you'll tighten a nut until the parking brake engages firmly within 3-5 clicks. Ensure both rear wheels lock up evenly when the parking brake is fully applied.
11. **Road Test:** Carefully drive your Tercel in a safe area, performing several stops from varying speeds. Listen for any unusual noises and feel for proper braking action. Remember that new shoes need a
