Chemicals that work well are great!
At the same time that the brake pads, which should have been thicker at first, are gradually reduced, the amount of exposed caliper pistons gradually increases. The dirt accumulated on the periphery of this piston becomes the "source of piston damage. After cleaning up the caliper piston periphery, the removed dirt is rinsed off with parts cleaner and air blown.
After that, spray MR20 metal rubber and push the piston into the caliper, and the piston operation will be remarkably improved afterward.
Even more effective with old car iron pistons!
If you compare it with the caliper piston image before the work, you will clearly see its beauty and finish. The key point is not to expose the piston too much. If the piston is exposed too much, it will be removed from the caliper body. This method will definitely give you a good result without disassembling the caliper!
POINT
Point 2 - Caliber piston contamination can be cleaned earlier and earlier to lengthen the consumable parts replacement cycle.
Point 3 - CLEANING can also improve braking and sustain it!
It is no exaggeration to say that the first step in brake maintenance is to clean the area around the brake calipers. In particular, it is well known that gravel and shavings from the pads tend to accumulate near the brake pads during riding. These impurities are trapped between the friction surface of the pad and the sliding surface of the rotor, causing the rotor sliding surface to become uneven and worn. When we ask the owner about this, we often hear that the brake calipers have been cleaned frequently and that the vehicle has never been used in the rain. In other words, just by thoroughly cleaning up, you can prolong the life of your valuable parts.
What is important about the brake unit is its absolute braking power and good controllability.
The latter, in particular, makes braking operation at will and makes driving more enjoyable.
Especially in circuit driving, there are many situations where control performance is more important than braking power. If you feel that the pads are a little too effective, you can change the pad choice to suit your preference.
Brake calipers can be restored to improved control without disassembly and maintenance.
Specifically, the pads should be removed to expose as much of the piston as possible (not too much, or the piston will come off!), and the dirt around the periphery of the piston should be removed. This is the only way to improve the condition of the brakes beyond your imagination.
For mild dirt, use a toothbrush; for heavy dirt, use a brass brush and a fine non-woven sheet.
After polishing, spraying MR20 Metal Rubber, a chemical that improves the operation of the metal and rubber, will improve the operation at once, and the touch of the brake lever will be surprisingly improved.
