“Running In” New Car Parts

It takes time to run in new car parts like tyres

While buying new car parts can be an expensive and daunting process, it’s also a vital one in maximising the performance, reliability and efficiency of your car. Even if it’s only a relatively small part, such as a gasket or a type of oil, it will need to be what is often referred to as “run in” before it is able to start boosting your car’s performance.

It’s true to an extent that a lot of new car parts will start working instantly, making a rapid improvement to the performance or efficiency of your car, but others will need a bit of extra time in order to get up to full working order.

Whenever you buy a new part for your car it’s highly likely that you’ll be advised to “be careful” for the first 100 miles while the parts adjust to the car – this is what they mean by running them in.

How to run in new car parts

The best practice when it comes to running in new car parts is to still drive the car, but to allow more time for the parts to start working. As you get used to driving your car you start to learn when you might need to brake, for example, trusting your brakes and tyres to slow down the car in a safe distance.

However, brake parts and tyres are actually the most difficult car parts to “run in”, because you have no choice but to use them. With other parts, like windscreen wipers or headlights, you can use them infrequently to start with (during the day or when using screenwash in these instances), so that they are ready for action when it goes dark or starts raining.

In the case of brake pads and discs, the best way to run them in is to keep using them. That may sound strange, but they both come with a protective ‘film’ that needs to wear away before they can have the maximum effect on the wheels.

The same is true with your tyres. Brand new tyres are often coated with a substance that will keep them in prime condition for customers buying them, and this reduces the amount of grip to an extent. It is only by taking your car out on the open road, taking corners and braking, that this protective layer will come away and bring your new tyres into “prime” condition.

The most important thing to remember is that when you get into your car after having any kind of new parts fitted they are going to feel slightly different to the parts they’ve replaced. New brake parts, for instance, will feel more efficient than the ones you have just taken off the car and that’s because you have subconsciously got used to how the old ones were performing.

You will need to allow more time for these parts to work, and for you to get used to them, and then you’ll start to realise just what you’ve paid your money for.
