The Shimano BR-5700 [paid link] brakes, part of the popular 105 groupset, are known for reliable stopping power, clean design, and mid-range performance ideally suited for enthusiast road cyclists. Yet, when it comes to installing these caliper brakes, cyclists often face the dilemma: should you tackle the installation yourself or entrust it to a professional mechanic? This guide will explore both paths in detail to help you make the right decision for your skill level [paid link], tools, and riding demands.
Understanding the Shimano BR-5700 Brakes
The BR-5700 [paid link] is a dual-pivot side-pull caliper brake designed for road bikes using rim braking systems. Its robust design includes symmetrical pivots and a lightweight alloy body, making it highly effective for all-weather riding. Installation precision is key to extracting maximum braking performance. Misalignment, improper torque, or poor cable routing can significantly reduce braking efficiency or cause premature component wear.
Tools Required for Installation
To properly install the BR-5700 [paid link] brake calipers, you’ll need the following tools:
- 5 mm Allen wrench [paid link] (for caliper mounting bolts)
- Torque wrench [paid link] with Allen head attachment
- Cable cutters (for inner and outer cable trimming)
- Needle-nose pliers (for pulling cable taut)
- Cable end caps and crimping tool
- Phillips screwdriver (for brake pad toe-in adjustment)
- Brake cable housing and inner wire
- Ruler or caliper (for alignment checks)
- Light grease (for bolt threads and cable friction points)
DIY Installation: What to Expect
Installing the Shimano BR-5700 brakes yourself offers a rewarding, hands-on experience. It allows you to understand how your bike functions and helps with on-road troubleshooting. However, success depends heavily on mechanical skill and tool access.
Key Steps in DIY Installation:
Start by mounting the calipers into the brake bridge and fork crown. The mounting bolt should pass through the frame’s brake hole, then be torqued evenly. Brake arms must center over the wheel, with equal spacing on both sides of the rim. Centering can be fine-tuned using the spring tension screw.
Next, thread the brake cable through the lever, housing, and caliper anchor bolt. Pull the cable taut while squeezing the calipers slightly against the rim to approximate pad clearance. After tightening the anchor bolt, use the barrel adjuster to fine-tune pad engagement and travel.
Lastly, adjust brake pads for toe-in. The leading edge should contact the rim just before the trailing edge. This minimizes brake squeal. Pads must be aligned so they contact the braking surface fully without touching the tire or dipping below the rim.
Challenges of DIY Installation:
- Achieving correct cable tension without a stand or third hand tool
- Ensuring both pads hit the rim simultaneously
- Accurately setting torque values without a torque wrench [paid link]
- Misjudging toe-in, which can lead to squealing or pad misalignment
DIY installation is viable if you’re experienced or willing to spend time learning. It’s a cost-saving option but can introduce long-term issues if not done correctly.
Professional Installation: What to Expect
A professional mechanic will install your BR-5700 brakes with precision and attention to detail. Shops use torque wrenches, alignment gauges, and cable tensioners to ensure optimal installation. More importantly, a trained mechanic understands how to evaluate the overall brake system — including lever pull, cable friction, and brake pad wear — which DIYers often overlook.
Advantages of Professional Installation:
- Guaranteed correct alignment, pad placement, and centering
- Consistent cable tension and clean routing
- Expert assessment of rim wear, pad compound suitability, and housing condition
- Reduced risk of component damage due to overtightening or misalignment
Professional service also typically includes a test ride, ensuring lever feel and stopping performance meet safety standards. This added layer of quality control is especially useful for riders with carbon rims or those prepping for competitive events.
Cost Comparison
While a DIY approach primarily involves tool and component costs, professional installation adds labor charges, usually ranging between $30–$60 depending on the shop and region. However, incorrect installation can lead to greater costs down the line—damaged wheels, accelerated pad wear, or reduced braking performance.
Who Should Choose DIY Installation?
DIY is best suited for:
- Riders with moderate to advanced mechanical experience
- Cyclists with a full home workshop setup
- Those interested in learning and maintaining their own bikes
It requires patience, careful adjustment, and regular post-installation checks, especially after the first few rides.
Who Should Opt for Professional Installation?
Professional installation is recommended for:
- Beginners without experience in cable-actuated brake systems
- Cyclists who prioritize performance and safety over cost
- Riders preparing for races or long-distance events
- Anyone installing brakes on carbon frames or integrated systems
Long-Term Maintenance Considerations
Whether you install the BR-5700 yourself or use a pro, regular maintenance is key. Check cable stretch, pad wear, and caliper centering monthly. DIYers must be especially vigilant, while professionally installed systems generally stay dialed longer if properly maintained.
Conclusion
The choice between DIY and professional installation for the Shimano BR-5700 brakes depends on your mechanical confidence, tool access, and performance expectations. DIY offers learning and cost-saving opportunities, while professional service ensures optimal function and safety from the start.
If you’re uncertain, consider a hybrid approach—install the brakes yourself, then take the bike to a shop for inspection and tuning. This strikes a balance between learning and performance.
