How do rear brake discs work?
The brake disc is a metal plate mounted on the wheel hub that is clamped between 2 rear brake pads when braking is applied; this causes friction and slows the vehicle down.
How often should brake discs need replacing?
As a rough guide, your** brake discs** should last between 50k and 70k miles, but there are many variables that could affect this, including driver behaviour, the weight you carry and the speed you travel.
The law, vehicle regulations and your MOT
Nearly 20% of MOT failures are caused by faulty brakes. Incorrect brake function, damaged or excessively worn discs or pads are considered unsafe for your vehicle performance and will cause your car to fail its MOT.
What causes rear brake discs to stop working correctly?
Rear brake discs wear out over time from continual use. The friction applied by the brake pads, and the intense heat generated, will eventually deform the disc, causing it to become thinner and less effective when performing its job.
Extended use can also cause rear brake discs to crack, rendering them ineffective. Scars and rust on the disc can be caused by debris thrown from the road and poor weather conditions; this is also effective in reducing the operation of your brake discs.
Symptoms of malfunctioning rear brakes
Braking causes unusual noises
Loud screeching or grinding noises from your brakes is an indication that there is a problem with either your brake discs or pads.
When your car pulls to one side under braking
If only one brake is working correctly, it can cause your car to pull in the direction of the functioning brake.
The car vibrates under braking
Your brake pads or discs could be warped if the pedal vibrates when you press down on it.
The brake disc shows signs of damage
Look through the wheel for a visual check—if the disc’s surface isn’t smooth, or it displays cracks, grooves, spots or a blue colourisation, then the disc is quite likely damaged.
Your brake warning light on the dashboard is illuminated
If any of your dashboard warning lights are illuminated, the sensor that detects problems or worn out parts and components has identified an issue and activated the system.
DS is the premium automobile marque of the Groupe PSA.
First announced in 2009 by Citroën as its premium sub-brand; it was suggested to be an abbreviation of different spirit or distinctive series. However, in French, the name is considered a play on words, as the translation of déesse becomes goddess in English.
How popular is DS in the United Kingdom?
As a newcomer to the UK market in its own right, there were around 35k DS cars on the roads in the UK by the end of 2018. Whether those figures will continue to rise at the same rate shown since their introduction in 2015, only time will tell.
Looking to provide a standalone marque to initially compete with brands such as Volkswagen and Audi, PSA decided that neither Citroën nor Peugeot would be able to carry the brand strength that would be able to make a serious threat in the market with an elevated price-point at the level of quality and luxury they set out to achieve.
DS: Establishing a new range of upmarket models
To compete with the likes of Audi, BMW and Mercedes-Benz, DS introduced a range of hatchbacks, saloons and SUVs but it’s undoubtedly their supermini city car that is proving the most popular.
The DS3, sold as a 3-door hatchback or a convertible, is available in countless customisation options and also as the subcompact luxury crossover SUV DS3 Crossback. The DS3 was voted Car of the Year by Top Gear Magazine, and first place supermini four times in a row in the JD Power Satisfaction UK Survey.
DS: Don’t be fooled into thinking they’re just a one trick pony
At the other end of the range you’ll find the DS7 Crossback. Here’s a large SUV designed to compete directly with the Audi Q5, the BMW X3 and the Mercedes-Benz GLC; that’s quite a jump for a car that’s built by Citroën.
The models that you’ll find between the DS3 and the DS7 are created with the same style for the market in mind. The DS4, a mixture of hatchback and SUV, and the DS5, a bigger hatchback priced and pitched against the Audi A4, the BMW 3 Series and the Mercedes C-Class saloons.
DS’s reliability and reputation
DS didn’t feature in the 30 car brands of the What Car? Reliability Survey in 2018, however, Citroën came in at 25th place so it stands to reason that their premium vehicles should score higher. Not necessarily so. Jaguar, Mercedes-Benz and Land Rover were propping up the wrong end of the survey, and given that the most reliable brands are all Asian manufacturers (with Suzuki, Lexus, Toyota, Kia and Mitsubishi taking the top spots) perhaps it’s simply a case of the rest of the world are having to play catch-up?
