Proper care of your Shimano BR-5700 [paid link] brakes is essential for preserving their braking efficiency, safety, and longevity. This dual-pivot caliper brake model, part of Shimano’s 105 series, is widely used by road cyclists for its balance of performance and affordability. However, without regular cleaning and selective lubrication, the performance of the BR-5700 [paid link] can degrade over time due to dirt buildup, corrosion, or worn-out components.
This guide will walk you through the optimal cleaning and lubrication routine, ensuring your BR-5700 [paid link] brakes deliver consistent stopping power and smooth operation for thousands of kilometers.
Understanding the BR-5700’s Maintenance Needs
The Shimano BR-5700 brakes use a spring-tensioned dual-pivot system, which relies on precise caliper movement, clean brake arms, and functional return springs. Since these components are exposed to road grime, water, and brake pad dust, their maintenance isn’t optional—it’s critical.
While lubrication should never be applied to braking surfaces like pads or rims, the pivot bolts and spring mechanisms benefit from targeted application to prevent corrosion and maintain proper return tension.
Cleaning the Shimano BR-5700 Brakes
Routine cleaning prevents performance decline and reduces premature wear. Clean your brakes every 300–500 km under dry conditions or more frequently in wet, dirty environments.
Step-by-Step Cleaning Process
Start by removing the wheels for clear access to the calipers. Use a soft-bristled brush to dislodge loose dirt and debris from the brake arms and mounting areas. Then, apply a mild degreaser (citrus-based or bike-specific) to the caliper arms, making sure not to get any on the brake pads or rims.
Use a microfiber cloth to wipe the surfaces thoroughly. Pay special attention to the pivot areas, where grime often accumulates. For stuck-on residue, a small brush or an old toothbrush helps reach tight corners.
After degreasing, rinse the calipers lightly with clean water and dry them completely with a clean cloth to prevent rust formation.
Lubrication Points on the BR-5700
Lubrication should be minimal and precise. Over-lubing is a common mistake that can attract dirt or contaminate braking surfaces.
Where to Lubricate:
- Pivot Bolts: These are the most critical lubrication points. A small drop of light bicycle oil (e.g., PTFE-based) on each pivot will keep the caliper arms moving smoothly.
- Return Spring Contact Points: A touch of lube where the return spring interfaces with the caliper body can enhance return speed and reduce squeaks.
- Cable Stop and Barrel Adjuster: While not technically part of the brake body, these components should be kept smooth to preserve precise modulation.
After lubrication, actuate the brake arms a few times to distribute the oil evenly. Always wipe off excess oil to prevent contamination.
Pad and Rim Surface Maintenance
Although lubrication isn’t applied to pads or rims, they still require attention. Inspect the pads for embedded debris, which can scratch rims or cause pulsing. Use a pick or a small flat tool to remove foreign material.
Clean the braking surfaces of the rim with isopropyl alcohol and a clean cloth. This removes residue and restores friction for optimal braking.
Routine Maintenance Intervals
To extend the lifespan of your BR-5700 brakes and keep them performing at their peak, adopt the following schedule:
| Task | Recommended Frequency |
|---|---|
| Visual inspection | Every ride |
| Surface cleaning | Every 1-2 weeks or 300–500 km |
| Full cleaning and lubrication | Every month or 1,000 km |
| Pad surface inspection | Monthly |
| Rim cleaning | Every 2 weeks or after wet rides |
Adhering to this routine can dramatically reduce mechanical wear and ensure consistent braking force under all conditions.
What to Avoid During Maintenance
- Avoid oil near the pads or rim surfaces. Contaminated pads must be replaced immediately.
- Do not use solvent-based cleaners that may degrade plastic or rubber parts.
- Do not over-lubricate. More oil doesn’t mean better performance; it usually means more dirt.
Storing Your Bike Properly
Even with perfect maintenance, poor storage conditions can negate your efforts. Keep your bike indoors or in a dry, protected space. Humidity and dust are primary enemies of the BR-5700’s small moving parts.
If you store your bike for more than a month, consider lightly reapplying lubricant to the pivot bolts before the next ride, especially if stored in a variable-temperature area like a garage or shed.
FAQs
1. How often should I clean the BR-5700 brakes in winter or wet conditions?
In winter or wet conditions, clean your brakes at least once a week. Salt, grime, and water accelerate wear and corrosion.
2. Can I use WD-40 on my BR-5700 brakes?
WD-40 is not recommended for lubrication as it evaporates quickly. Use a dedicated bike lube for the pivots and springs.
3. How do I tell if I over-lubricated the brakes?
If you notice oily residue near the pads or rims, or if braking feels inconsistent, you may have over-lubricated. Clean immediately and reapply minimally.
4. Do I need to remove the brake calipers to clean them?
In most cases, no. Removing the calipers is only necessary for deep maintenance or overhaul. Most cleaning can be done with them mounted.
5. Is it okay to use compressed air to dry the calipers?
Yes, but use low pressure to avoid forcing debris into tight spaces or damaging seals.
6. Can I apply grease to the brake pivots instead of oil?
Light oil is preferred. Grease may attract too much dirt and impede movement in tight pivot areas.
Conclusion
Regular and precise cleaning and lubrication of your Shimano BR-5700 brakes ensure smooth operation, optimal braking power, and longer component life. By targeting only the correct areas for lubrication and avoiding contamination of braking surfaces, you can maintain top-tier performance from your BR-5700 setup for years.
