Brake Master Size Review

Main Points

• The reviewer uses an RCB S1 brake master with a 14 mm piston.
• He says RCB and KTC masters are available in 14 mm and 17 mm sizes, but he is unsure whether a 19 mm option is also available.
• His front brake setup uses two RCB S1, two-piston calipers in a double-disc system, for four pistons total. The rear brake remains mostly standard.
• With this setup, the reviewer finds that the 14 mm master works, but braking still feels a little weak. He thinks a 17 mm master would be a better match.
• For motorcycles with standard front brakes, he recommends a 14 mm master as sufficient. He says a 17 mm master can make braking feel very strong; a friend uses one, and the reviewer has tried it.
• The price difference between sizes is approximately Rp500,000, though the reviewer is unsure and invites corrections.
• When upgrading a master or caliper, he recommends replacing the standard brake hose with a racing brake hose. He says standard hoses can stretch, while racing hoses maintain their dimensions more consistently. In his view, even an inexpensive racing hose is preferable to keeping the original hose.
• He also mentions caliper-cooling accessories on his bike. He considers them mostly cosmetic, though their openings may provide some airflow and a small functional benefit.

Pros and Cons

Pros

• A 14 mm master is presented as adequate for standard brakes and may suit tighter budgets.
• A 17 mm master is described as providing a stronger-feeling brake response, particularly compared with the reviewer’s 14 mm setup on double discs.
• Upgrading the brake hose is recommended to help maintain stable hose dimensions.

Cons and Caveats

• The reviewer’s 14 mm master feels somewhat underpowered with his double-disc, four-piston setup.
• A 17 mm master may feel very strong, especially on standard brakes.
• The approximate price difference is uncertain, and the video provides no measured braking tests or formal performance scores.

Verdict

Choose the master size to match the brake setup and budget: 14 mm for standard front brakes; 17 mm is the reviewer’s preferred direction for his double-disc, four-piston arrangement. Consider upgrading the brake hose alongside the master or caliper.
