A year of stop-start braking, in millimetres
West Street and Wrythe Lane carry hospital traffic, buses and visitors to St Helier all day, and the A232 through the village by Honeywood Museum and Grove Park is narrow, parked up and slow. Almost every local journey involves repeated light braking, which is the pattern that wears pads evenly and quietly rather than suddenly. You rarely notice it until there is a noise, by which point the discs are usually involved too.
At a full service all four wheels come off. Pad thickness and disc thickness are measured, the condition of the inner pads is checked as well as the outer ones, and the numbers go on your report so you can see what a year of this driving has actually cost. That is a different exercise from a glance through the wheel spokes, and it is why the service takes two to three hours rather than one.
The brake fluid gets tested for moisture at the same time. Fluid absorbs water from the air through the reservoir and the flexible hoses, and once it is past roughly three per cent it can boil under sustained braking and leave you with a long pedal. Climbing and descending Park Hill up to Carshalton on the Hill is exactly the sort of use that finds it out. If the reading is high we will tell you and quote for a change.
The rest is the annual work proper: engine oil and oil filter, air filter, coolant strength test, battery and charging check, a fault code scan and a road test before you get the car back. Anything extra is quoted in writing first, repairs carry our 3-month workmanship guarantee, and at 1.2 miles away collection is rarely needed. If anything does need booking in, you are five minutes from the bench it will be done on.
