Upgrading Hydraulic Disc Brakes: Tips and Tricks for Optimal Performance
When it comes to maintaining and upgrading your hydraulic disc brakes, there are several important considerations to keep in mind. This guide will provide you with valuable insights and tips to help you achieve the best possible performance from your brake system.
Add Brake Fluid Properly
One of the most common questions about upgrading hydraulic disc brakes is when to add brake fluid. Unlike what some might think, you should not just add brake fluid under normal circumstances. The fluid should only be added if there is a noticeable leak or if the brake service requires it. Adding brake fluid unnecessarily can lead to several issues, especially when the brake pads are changed. This is particularly true if the pad wear is the reason for substituting the pads, as adding fluid can upset the balance and effectiveness of the brake system.
The correct procedure involves checking the brake fluid level in the reservoir. Look for a clear reservoir, and ensure the fluid level does not drop below the minimum mark. Unscrew the lid and top up to the maximum level mark, using only brake fluid. Never mix other fluids or liquids into the brake system as this can cause serious damage to your hydraulic braking system.
Simple Upgrade Options for Improved Handling
Improving your brake setup can be as simple as swapping out the rubber brake hoses for braided stainless steel ones. This upgrade is not only inexpensive but also provides a range of benefits. Braided stainless steel hoses offer improved durability and resistance to heat, and they can help reduce the sponginess of the brake lever or pedal. Although this upgrade doesn't necessarily make the brakes more powerful, it does make them feel more responsive and less effort is required to engage the brakes. This is particularly noticeable in older or higher mileage vehicles where the original rubber hoses may have degraded over time.
While similar upgrades can be carried out on cars, these types of hoses are more commonly found on motorcycles because the maintenance can be simpler. This upgrade is not just for performance enthusiasts; it is a practical choice for everyday riders looking to reduce the effort required to apply the brakes and improve the overall riding experience.
Matching Components for Optimal Performance
When upgrading your hydraulic disc brakes, it's crucial to ensure that the components match in terms of ratios. This is especially important when replacing master cylinders or callipers. For instance, if you're upgrading to a higher capacity master cylinder, ensure the replacement calliper is designed to handle the increased volume of fluid.
A great example of this is the combination of a Triumph Bonneville's original master cylinder with a 6-piston calliper, using beaded hoses and a good disc. Such a setup can significantly improve braking performance, provided the components are matched correctly.
Advanced Upgrades for Track Use
For track use, the goal of upgrades is to enhance heat dissipation so that the brakes remain fully effective even when very hot after repeated heavy use. Some enthusiasts go as far as adding a second caliper around the brake disc, although a simpler upgrade would be to fit ceramic pads. Ceramic pads offer several advantages, including better high-temperature performance, reduced dust and noise, and longer life compared to traditional organic pads.
It's also worth noting that in track applications, the effectiveness of the brakes is heavily influenced by the grip between the tires and the road. Therefore, any upgrade should be in service of better heat management rather than just increasing brake force.
Remember, each upgrade should be carefully considered based on your specific needs and the condition of your existing brake system. Always refer to the manufacturer's guidelines and seek professional advice if you're unsure about making any modifications.
