When discussing the history of mountain bike disc brakes, Hayes is a name that frequently emerges, synonymous with pioneering performance and robust reliability. While the market has seen an explosion of new technologies and brands over the years, the question often arises: are Hayes disc brakes still a good option? Specifically, the Hayes Nine model holds a special place in the hearts of many riders and mechanics. Having put hundreds of sets of Hayes Nine brakes through their paces in our years of rigorous bike testing, we can confidently say these faithful speed eaters remain some of the best basic brakes around, especially for those who appreciate simplicity and steadfast performance.
The Enduring Legacy of Hayes
Hayes Brakes, originating from the USA, were among the first manufacturers to bring reliable, mass-produced hydraulic disc brakes to mountain biking. In an era dominated by V-brakes and early, often temperamental, hydraulic systems, Hayes offered a significant leap forward. Their systems were known for their consistent power, reasonable modulation, and, crucially, their ability to withstand the harsh demands of off-road riding. The Hayes Nine, in particular, became a ubiquitous sight on mountain bikes through the early to mid-2000s, establishing a benchmark for what a dependable disc brake should be.
Diving Deep into the Hayes Nine
The Hayes Nine wasn't just popular; it was a workhorse. Its design prioritised function and durability, making it a favourite for everything from cross-country to aggressive trail riding and even early freeride. Let's break down what made them stand out:
Performance & Feel: Power and Modulation
At its core, the Hayes Nine delivered. Stopping power was ample for its time, providing a reassuring bite that allowed riders to push harder and descend with greater confidence. While modern brakes might offer more outright power or a different lever feel, the Nine's power was predictable and consistent. Modulation – the ability to control braking force smoothly – was respectable. Riders could feather the levers to scrub speed without locking up, which was essential for maintaining traction on loose or technical terrain. The lever feel was often described as firm and direct, giving a good connection between the rider's hand and the caliper's action.
Built to Last: Reliability & Durability
Perhaps the most celebrated aspect of the Hayes Nine was its durability. These brakes were built like tanks. The calipers and levers were robust, designed to take a beating on the trails without complaint. It wasn't uncommon to see Hayes Nine sets still performing admirably years after their initial purchase, often outliving the bikes they were originally fitted to. This longevity contributed significantly to their reputation as a solid, reliable choice for riders who prioritised function over the latest lightweight trends.
Simplicity in Maintenance
Another strong point for the Hayes Nine was its relative ease of maintenance. The open hydraulic system was straightforward to bleed, even for home mechanics. Using common DOT 4 or DOT 5.1 brake fluid, which is widely available, simplified servicing. Pad changes were also a quick and simple affair, making on-trail or pre-ride adjustments hassle-free. This user-friendliness further cemented their appeal among riders who preferred to do their own bike work.
Who Were They For? (And Who Are They For Now?)
In their prime, Hayes Nine brakes were a versatile option, suitable for a wide range of mountain biking disciplines. They were found on everything from budget-friendly hardtails to higher-end full-suspension bikes. Today, while no longer produced new, they remain a fantastic option for classic bike builds, restoration projects, or as an affordable and dependable replacement for older, less reliable braking systems. Their enduring robust nature makes them a sensible choice for riders seeking a no-nonsense, functional brake without breaking the bank on second-hand components.
Key Technical Specifications & Features
The Hayes Nine utilised an open hydraulic system, which means the reservoir is open to the atmosphere (via a diaphragm) to compensate for fluid expansion and contraction, offering consistent lever feel. They typically used 6-bolt rotors, a standard that persists today. The calipers were a two-piston design, offering good clamping force. While perhaps not as aesthetically refined as some modern brakes, their functional design was undeniable.
Hayes Nine vs. Modern Disc Brakes: A Comparative Look
It's important to set expectations when comparing the Hayes Nine to contemporary braking systems. While the Nines were excellent for their era, technology has moved on. Here's a brief comparison:
| Feature | Hayes Nine (Era: Early 2000s) | Modern Hydraulic Disc Brakes (e.g., Shimano Deore, SRAM Level) |
|---|---|---|
| Stopping Power | Good, reliable, consistent | Excellent, often more powerful, sharper initial bite |
| Modulation | Respectable, predictable | Often more refined, wider range of control |
| Weight | Heavier by modern standards | Significantly lighter (due to advanced materials & design) |
| Ergonomics | Solid, functional, often bulky levers | More refined lever shapes, tool-free reach adjust, sometimes bite point adjust |
| Pad Availability | Still good, many aftermarket options | Excellent, wide range of compounds |
| Fluid Type | DOT 4/5.1 | DOT 4/5.1 or Mineral Oil (brand dependent) |
| Maintenance | Straightforward bleeding, robust | Often simple, but can be more complex with advanced features |
| Price (New/Used) | N/A (new), excellent value (used) | Wide range, from budget to premium |
As the table highlights, modern brakes have certainly advanced in terms of weight, ergonomics, and often outright power. However, the Hayes Nine still holds its own in terms of fundamental stopping ability and, crucially, its legendary reliability and simple maintenance. For a budget build or an older bike, the performance difference might not justify the cost of new, higher-end brakes.
Keeping Your Nines Running Smoothly: Maintenance Tips
If you're running Hayes Nine brakes, a few simple maintenance steps will keep them performing optimally:
- Regular Bleeding: Even though they're robust, fresh DOT fluid ensures consistent lever feel and prevents fluid degradation. Bleed them at least once a year, or more often if the lever feel becomes spongy.
- Pad Inspection: Check your brake pads regularly for wear. Replace them before they wear down to the metal backing plate to avoid rotor damage and maintain braking performance.
- Rotor Cleanliness: Keep your rotors clean and free of oil or grease. Contaminated rotors can severely reduce braking power and cause annoying squealing.
- Caliper Piston Cleaning: Occasionally, gently push back the pistons (with pads removed) and clean the exposed piston walls with isopropyl alcohol. This helps prevent sticking and ensures smooth pad retraction.
The Verdict: Are Hayes Nine Brakes Still Worth It?
Absolutely. While they might lack the cutting-edge features and feather-light weight of their modern counterparts, Hayes Nine brakes remain a highly competent and remarkably dependable braking system. For riders on a budget, those restoring a classic mountain bike, or anyone who values robustness and ease of maintenance above all else, the Hayes Nine is an exceptional choice. They deliver consistent, strong stopping power, are incredibly durable, and are relatively simple to service. They embody the principle that sometimes, simpler is better.
