Welcome to Roberts Tyres in Sleaford 

On this page, we would like to give you some information about the brake system in your car and also about our brake service. We hope you will find this information useful. If you have any questions, please get in touch with us. 

When do you need to replace brake pads and brake discs? 

If there is a grinding noise during the drive or the wear indicator is lit on your vehicle's dashboard, it is high time for a brake service.  

Here our Roberts Tyres experts will tell you all you need to know about brake pads, brake discs and replacement intervals. 

The brake system in the car is essential for vehicle safety. But what must be considered when changing brake discs and brake pads?  

What types of brake systems are there? 

Basically, there are almost always disc brakes in modern cars. These are now widely used and have largely replaced the older drum brake systems. In cars with low power and small cars, they are occasionally still installed on the rear axle. 

A disc brake system consists of a rotating disc mounted on the wheel hub. To achieve a deceleration of the vehicle, brake pads with brake linings are pressed against the discs. 

In a drum brake system, however, the brake pads are not pressed against a disc, but against a rotating drum, so that in this way a delay is achieved. 

Note: The following information applies to the disc brake systems. 

When is the time for a change? 

Not always all the wearing parts of the brake system must be renewed: 

Brake discs should always be changed when the wear limit is reached. Deep grooves or uneven wear also require replacement. 

A grinding- and rubbing noise when braking is normally an indicator of the insufficient strength of the brake pads.  

What are the usual replacement intervals? 

It is recommended that the brake system should be checked for wear approximately twice a year. This is useful, for example, when changing the tyres or the wheels. 

The most common wear parts are the brake pads and the brake discs. Less often, the calliper must be replaced. Irrespective of the wear on these parts, the brake fluid must be replaced regularly. 

How often the components have to be changed is hard to say. The reason for this is that the driving style and the material condition have a great influence on the actual service life. 

It is also important to know that when changing the brake discs, you should always have the corresponding brake pads replaced. In the opposite case, however, replacement of the brake discs when changing the brake pads is not necessarily required, unless the brake discs are really worn out. However, if only the discs are replaced and the pads maintained, it may also come to lower braking performance or faster wear and rubbing noise. 

In addition, brake discs and brake pads should always be changed axle by axle. 

What happens in the workshop? 

To replace the wearing parts, the vehicle is first put on the ramp. Then the wheels are disassembled so that the brake system is freely accessible. 

In the next step, the calliper is disassembled, so that the brake pads and possibly also the brake discs can be replaced. If the brake discs are changed, the calliper support must be dismantled in most cases. In any case, the brake piston(s) must be reset since the new pads or the new discs are thicker. 

Then the wheels can be mounted and the vehicle lowered. Finally, a function check takes place. 


At the latest when wear indicators let you know that there is too much wear, or if you can hear annoying grinding and rubbing noises while driving, the components of the brake system should be replaced. A change of the brake discs should always be accompanied by an exchange of the brake pads - the other way round this is not always necessary. Here at Roberts Tyres we only change what needs changing. We want to save our customers time and money. 

We only use the best quality replacement parts to make sure you will be safe on the road at all times. It is important that the replacement of individual components always takes place on the entire axle and thus on both sides of the vehicle.
