Replacing the brake pads on a single axle usually takes between 30 and 90 minutes, provided the system is in good working order and the caliper bolts and guides are not corroded.
However, the total duration of the visit can be longer, as it includes diagnosis, checking the condition of the brake discs and brake fluid, and a short test drive after fitting. We operate 24 hours a day, seven days a week, so you can book an urgent brake pad replacement with us without having to wait for an available slot during normal workshop opening hours.
In short
- Replacing the brake pads on a single axle typically takes 30–90 minutes, provided the system is in good working order.
- Corroded bolts and calipers, an electric parking brake and the need to replace discs will extend the service time.
- Cars with an electric parking brake require a diagnostic computer to retract the caliper pistons.
- Our workshop operates 24 hours a day, so there’s virtually no waiting time for an available slot.

How long does it actually take to replace the brake pads on a single axle?
Replacing the brake pads on a single axle – assuming the system is in good working order and there are no additional complications – takes between 30 and 90 minutes, depending on the car model and the design of the caliper. City cars and compact cars with easier access to the brakes usually fall closer to the lower end of this range, whilst larger SUVs and cars with complex electronic systems take longer. On top of the actual fitting, there is also the removal and refitting of the wheel, so the actual time spent on the hoist is often slightly longer than the time spent working on the caliper itself.
What causes the replacement time to exceed the standard 30–90 minutes?
The most common reason for the replacement time being extended is corroded caliper guide bolts, which, after years of use, can become seized and require additional time to clean or carefully unscrew without damaging the thread. A second factor is a brake caliper piston that is reluctant to retract, particularly in older cars, where contaminated brake fluid increases the resistance during this operation. A third, increasingly common reason is the need to replace the discs at the same time, which adds a further 20 to 40 minutes to the service to remove the old ones and fit the new ones.
Why does an electric parking brake require an extra step?
Cars with an electric parking brake have a small motor built directly into the rear axle caliper, which maintains pressure on the brake pads even after the car’s engine has been switched off. Before the mechanic can retract the piston and remove the old pads, they must switch the system to service mode using a diagnostic computer or a dedicated interface; otherwise, they risk damaging the mechanism. This extra step adds a dozen or so minutes to the rear axle replacement compared with a conventional mechanical parking brake.
How does the condition of the discs affect the total duration of the service?
If, during the inspection, it transpires that the discs need replacing along with the pads, the service time is extended to include the removal of the old discs, cleaning the hub of any traces of corrosion, and fitting the new components whilst ensuring the bolts are tightened to the correct torque. In practice, this means that replacing a set of brake pads and discs on a single axle usually takes between one and two hours, rather than the 30 to 90 minutes allocated for the pads alone. Therefore, an initial assessment of the condition of the discs before work begins allows for a realistic estimate of how long the car will spend in the workshop, rather than relying solely on the time specified for the pad replacement alone.
What do we check before and after the replacement, before handing the car back?
Before starting the replacement, we assess the condition of the discs, the level and colour of the brake fluid, and the condition of the flexible hoses to determine the actual scope of work before lifting the car onto the hoist. After fitting the new pads, we carry out a series of tests to check the system’s performance, and only then do we take the car for a short test drive to see how the brakes respond in practice, not just on the test bench. This extra step takes a few to a dozen or so minutes, but it reduces the risk of the customer returning to the workshop with a problem that could have been detected straight away.
Why is the waiting time at the garage sometimes longer than the repair time itself?
The time a car spends at the garage is not the same as the time the mechanic spends working on the brakes, because the visit also includes taking the vehicle in, assessing the scope of work and handing back the keys once the service is complete. If several cars are being serviced at the same time, your car may have to wait for a free bay, even though the brake pad replacement itself would take just 30 minutes. Booking a specific time slot rather than turning up unannounced reduces this waiting time to almost zero, as the mechanic can prepare the workstation and parts before the customer arrives.
When is the best time to schedule a replacement so as not to waste time?
It’s best to plan a brake pad replacement as soon as the first signs of wear appear, rather than waiting until the noises and vibrations become unbearable, as a routine visit takes less time than an emergency repair with damaged discs. As we work seven days a week, round the clock, including Sundays and public holidays, you can schedule a replacement at any time, without having to fit in with the typical opening hours of a car workshop on weekdays. This means that the decision on when to carry out the work is based on the actual condition of the brake pads, rather than on when you can just about find the time between 8 am and 4 pm.
Summary
- The actual replacement of the brake pads on a single axle usually takes 30–90 minutes if the system is in good working order.
- Rusted bolts, an electric parking brake and the need to replace brake discs will extend the service time.
- The time spent at the workshop is longer than the repair time itself, as it includes diagnosis and a test drive.
- Our workshop operates round the clock, so urgent replacements can be scheduled without having to wait for an available slot.
