When buying a used car, people often see rust on the brake discs, but don’t pay attention to it. Indeed, a light coating on the working part of the disc only indicates that the car has stood motionless for a long time. But rust in other places can be quite dangerous. What to pay close attention to when inspecting the brakes, the portal says “AvtoVzglyad”.
Usually only the outer parts of the braking mechanisms are inspected. But it is their internal surfaces that suffer the most from corrosion. If the car has no fenders, nothing prevents road chemicals and rocks from bombarding the rims. As a result, deep grooves form on the working surfaces, in which rust “settles”. As a result, there are vibrations on the handlebars during braking and the braking distance increases. One day this could lead to an accident. So during the inspection process, it would be good to lift the car on a lift and inspect the brakes from all sides. If you see rusty grooves, it is a signal that the discs need to be replaced and this is a good reason to negotiate.
Further. Scale will appear on the edges of the discs over time. It is formed by the fact that the disk is heated regularly, and dirt flies on it for years. The driver who keeps an eye on the car regularly tips the scales with a hammer. Failure to do so may cause lumps to form between the pad and the disc. This will cause the appearance of many grooves on the work surface. Well, what this will lead to is described above. You can only buy a car with such braking condition by asking for a substantial discount. And don’t forget to wear plastic safety glasses when cleaning the scale. If a bit of flash flies into the eye, the problems are serious.
By the way, rusty brake discs can spoil new brake pads, because then the disc will not look like a brake disc, but like an emery disc. In this condition, the life of the pads is halved. So don’t ignore rust or you’ll pay for another set of pads.
And rust can cause the rear brakes to lock up. This leads to heating of parts and if the pads are cheap, such a temperature increase can even cause a fire. Of course, it will not be the friction mixture that will burn, but the paint on the mounting plate, which will be applied so that this plate does not corrode. This is another reason not to save on brake pads, because road safety depends on it.
