Does Caliper Painting Affect Safety?
2 Answers
Caliper painting does not affect safety. Here is the relevant introduction to caliper painting: 1. Principle: The brake booster pump and the master cylinder are connected in series, usually appearing as a large black cylindrical or conical container. It is essentially a piston mechanism with a diaphragm inside that divides the booster pump into two chambers. One side is connected to the engine intake pipe, while the other side is exposed to the outside atmosphere. 2. Notes on caliper painting: (1) The paint used must be heat-resistant; (2) There are limited cleaning methods available. Many caliper surfaces are not smooth, so it is best to clean them thoroughly before painting. However, the paint will not last long due to the lack of protective measures, as it will inevitably be chipped by small stones, gravel, or brake dust after application.
I once painted my calipers as a personal hobby to enhance the car's appearance. The key is to use high-temperature paint that can withstand over 150 degrees Celsius, as the calipers heat up during braking. If the paint is too thin or not heat-resistant, prolonged use may cause overheating and affect braking performance. Before painting, the calipers must be thoroughly cleaned to avoid residual grease, and covering the cooling vents will prevent heat dissipation. I used professional automotive paint and did it myself several times without any braking issues, but beginners are prone to mistakes. It's advisable to test-spray a small area first and wait for it to dry completely before driving. Overall, it doesn't compromise safety if done correctly, but careless handling poses risks, so consider seeking professional help to avoid accidents.
