Cycling enthusiasts know that proper maintenance of their hydraulic disc brakes is crucial for safety and performance. The "sealantkit Brake Bleed Kit for Shimano" promises to streamline this often daunting task, allowing even novice mechanics to bleed their own Shimano brakes with ease and confidence. This comprehensive review will delve into the kits design, durability, functionality, ease of use, user feedback, price, and ultimately whether it lives up to its claims.
The Sealantkit Brake Bleed Kit is designed specifically for Shimano hydraulic disc brake systems. It's compatible with a wide range of Shimano models, including Deore, SLX, XT, and XTR brakes, as well as Tektro, Magura, and some SRAM models (though compatibility should be verified beforehand). The kit boasts a unique design that sets it apart from other bleed kits on the market. The main component is an innovative syringe system that replaces traditional syringes with refillable cartridges. This significantly reduces waste and eliminates the need to constantly replace disposable syringes. Each cartridge holds around 20ml of mineral oil, allowing you to bleed multiple brakes before needing a refill. The kit includes two cartridges one for Shimano Mineral Oil (included) and one that can be filled with DOT fluid for non-Shimano hydraulic systems. Other components include:
The Sealantkit Brake Bleed Kit feels robust and well-built. The plastic components are thick and durable, capable of withstanding regular use without breaking or cracking. The syringe cartridges feel solid, ensuring a tight seal and preventing leaks during the bleeding process. However, some users have reported that the pressure adapter can sometimes become loose over time, requiring periodic tightening. The hose cutter/crimper is made from sturdy metal but may not be as precise as professional tools, particularly for those new to brake maintenance. Nonetheless, it's a valuable addition for cutting and crimping hoses during repairs or upgrades. Overall, the kit demonstrates good durability, though occasional care and maintenance are recommended to ensure optimal performance.
The Sealantkit Brake Bleed Kit is designed to simplify the braking bleeding process. Its key advantage lies in its refillable syringe system, which significantly reduces waste and allows for multiple bleeds from a single purchase of mineral oil or DOT fluid. The cartridges are easy to fill with the included refill syringe, minimizing mess and hassle. The pressure adapter creates consistent pressure during the bleed process, ensuring efficient removal of air bubbles from the brake lines. This results in more responsive and powerful braking performance. Furthermore, the clear funnel allows for visual confirmation that all air has been purged, preventing incomplete bleeds. However, users with very stiff brakes may find it challenging to push the syringe plunger fully, even with the pressure adapter. This can sometimes require a second pair of hands or using a lever to apply more force. Additionally, some Shimano models have bleed ports that are difficult to access, making bleeding slightly more complex than other models.
The Sealantkit Brake Bleed Kit is designed for users with varying levels of mechanical skill. While it's not as simple as a one-button automatic bleeder, its step-by-step instructions and clear labeling make the process relatively straightforward to follow. However, some experience with bicycle maintenance can be helpful, particularly when identifying brake components and connecting hoses. The refillable syringe system is a major plus in terms of ease of use compared to traditional kits that require frequent replacement of disposable syringes. The included bleed block simplifies pushing the plunger without accidentally releasing oil into your pads. Overall, while the kit isn't entirely foolproof, its user-friendly and offers a significant improvement over using improvised tools or methods for bleeding brakes. The clear funnel also helps visualize progress during the bleeding process, reducing guesswork.
User reviews of the Sealantkit Brake Bleed Kit are generally positive, with many praising its refillable syringe system and ease of use. Many users appreciate the kit's compatibility with multiple brake systems and the included Shimano mineral oil. However, some have noted that it can be difficult to push the plunger on very stiff brakes, requiring extra effort or assistance. Heres a summary of common user feedback:
The Sealantkit Brake Bleed Kit for Shimano typically retails around $60-80 USD, which is comparable to or slightly higher than other high-quality brake bleeding kits on the market. While it's more expensive than disposable syringe kits, its refillable design and included accessories make it a cost-effective option in the long run. Considering the quality of construction, functionality, and user experience, the Sealantkit Brake Bleed Kit offers excellent value for cyclists who want to maintain their hydraulic disc brakes themselves. The kit is particularly attractive for those with multiple Shimano bikes or who frequently bleed their brakes due to heavy use or environmental conditions.
If you own a Shimano, Tektro, Magura, or SRAM hydraulic disc brake system and want an effective way to maintain your brakes without spending money on professional servicing, the Sealantkit Brake Bleed Kit is definitely worth considering. Its refillable syringe system, clear funnel, and user-friendly design make it significantly easier than traditional bleed kits. While pushing the plunger can be challenging on very stiff brakes, this issue is easily mitigated with a little extra effort or assistance.
