Painting brake calipers is a delicate process that is not without counter-indications. Based on our experience, we have identified 5 reasons why we suggest this not be done. Of course, everyone is free to form their own opinion and do what they feel is best on their vehicle.
We do not deny that there may be professionals who are able to execute this type of operation properly, but unfortunately we frequently receive reports of calipers that malfunction after undergoing a painting intervention that was carried out incorrectly. Obviously, it is not the paint itself that damages the calipers, but rather the preliminary operations conducted on the hydraulic part. Often the piston dismounting and mounting procedures are not carried out properly or, in some cases, not carried out at all. In this situation, if the caliper undergoes an “oven baked” painting process, the heat may damage the piston seals and jeopardise the performance of the caliper.
The variables affecting the process used and the professionality of those who carry out this intervention are numerous and difficult to anticipate. For this reason, Brembo simply discourages this type of operation on such a vital and important active safety component like the braking system.
