Performing these steps on a regular basis will help ensure the suspension remains in good working order. Brake maintenance is a key aspect of keeping your TR3 running smoothly. Brake pads and rotors should be inspected regularly for wear and tear. Brake lines should also be checked for any signs of leaking or damage, and brake fluid should be flushed periodically to ensure it is still in good condition. Taking the time to do these simple maintenance steps can help prevent brake issues in the future. Tire care is another important aspect of maintaining your TR3. Tire pressure should be checked regularly to make sure it is at the recommended level for your vehicle.

Tread depth should also be inspected to make sure it is not too low, as this can affect handling and braking performance. Balancing tires should also be done periodically to ensure they are wearing evenly. Finally, tires should be rotated regularly to help them wear evenly and last longer. Bodywork is an important part of keeping your TR3 looking its best. The exterior of the car should be washed and waxed regularly to keep it looking shiny and new.

Rust spots should also be inspected for and repaired if necessary. Any bodywork damage that has occurred should also be repaired promptly to prevent further damage from occurring. Taking the time to perform regular maintenance on your TR3 will help keep it running smoothly and looking its best for years to come. Following these simple steps will help ensure your classic car remains in great condition for years to come.


Bodywork maintenance is an important part of keeping a Triumph TR3 in good condition. Regular cleaning and waxing can help protect the body from dirt and rust, while inspecting for rust spots and repairing any damage can help prevent further wear and tear.

Cleaning and waxing the exterior of the car helps to protect it from dirt, debris, and UV rays which can cause fading. A good quality car wax should be used to protect the paintwork from environmental damage. Before applying the wax, it is important to wash the car thoroughly with a detergent specifically designed for car exteriors. Inspecting for rust spots is an important part of TR3 maintenance.

Rust can quickly spread if left untreated, so it is important to check regularly for any signs of rust. If rust is found, it should be treated as soon as possible with a rust-inhibiting product. Finally, any damages to the exterior of the car should be repaired promptly. It is best to use a professional auto body repair shop for any repair work that needs to be done.

This will ensure that the job is done correctly and that the car remains safe and reliable.

Brake Maintenance

Brake Maintenance - Inspecting brake pads and rotors, checking brake lines, and flushing brake fluid are all important tasks to ensure your Triumph TR3's brakes are working properly. It is important to inspect brake pads and rotors regularly to ensure they are in good condition. Worn out brake pads can cause the brakes to overheat, leading to potential damage to other parts of the braking system. In addition, worn out rotors can cause vibrations in the steering wheel when the brakes are applied.

To check the brake lines, look for any signs of corrosion or damage. If you notice any issues with your brake lines, you should have them inspected and repaired as soon as possible. Additionally, it is important to flush the brake fluid regularly to prevent build up of contaminants in the system. This should be done at least once a year to ensure proper brake performance.

Suspension Maintenance

Maintaining the suspension of a Triumph TR3 is essential for keeping it running smoothly.

Inspecting the shock absorbers, checking ball joints and bushings, and lubricating components are all important steps in keeping the car in top condition. Shock absorbers should be checked regularly to ensure they are functioning properly. Check for any signs of wear or damage, and replace any damaged parts as soon as possible. It is also important to check the shock absorbers for proper oil levels and adjust them if necessary.

Ball joints and bushings should also be inspected regularly. Signs of wear can indicate that these parts need to be replaced. When inspecting these components, it is important to look for any signs of corrosion or damage that could affect the performance of the suspension system. Lubricating components is also an important part of maintenance for the Triumph TR3. Lubricate all moving parts with a lubricant specified by the manufacturer.

This will help ensure that components are functioning properly and will reduce wear and tear on the suspension system.

Tire Care

Checking Tire PressureIt's important to check tire pressure regularly to ensure your TR3 is running safely and efficiently. Tire pressure should be checked when tires are cold, ideally first thing in the morning. The recommended tire pressure for a TR3 can be found in the owner's manual.

To check pressure, use a tire pressure gauge and inflate the tires as necessary.

Inspecting Tread Depth

In addition to checking tire pressure, you should also inspect the tread depth of your tires. This will help you identify any areas of wear and tear that need attention. If the tire tread depth is too low, it may be time to replace the tires. Use a tread depth gauge to measure the remaining tread on the tires and compare it to the recommended levels in the owner's manual.

Balancing Tires

Tire balancing is another important part of tire care.

It's necessary to balance your tires to ensure a smooth ride and reduce wear on tires and suspension components. To balance tires, have them mounted on a balancing machine at an automotive shop. This will help identify any issues with wheel alignment or tire weight.

Rotating Tires

Finally, it's important to rotate your tires regularly to ensure even wear across all four tires. Tire rotation patterns vary depending on the type of vehicle, so check your owner's manual for specific instructions.

Generally, it's recommended to rotate tires every 6,000-8,000 miles or every 6 months.

Engine Maintenance
