The Shimano BR-6700 [paid link] brakes, part of the Ultegra 6700 series, are known for their sleek design, consistent modulation, and reliable stopping power. However, like any high-performance road bike component, their performance can degrade over time without a proper care routine. Dirt, debris, and lack of lubrication are common culprits that compromise braking efficiency. This guide provides a model-specific maintenance routine for cleaning and lubricating your BR-6700 [paid link] brakes, ensuring longevity and optimal performance.

Why Cleaning and Lubrication Matter for the BR-6700

Brake calipers are constantly exposed to road grime, dust, water, and sweat—elements that contribute to corrosion, stiff pivots, and uneven braking. The BR-6700 [paid link] uses a dual-pivot design that benefits significantly from regular maintenance. Clean surfaces promote better pad contact, while smooth pivots ensure responsive lever action and power transfer. If ignored, contaminants can increase friction in the caliper arms, reducing brake feel and increasing wear on both pads and rims.

Tools Required

  • Allen keys [paid link] (typically 5mm for brake mounting bolts)
  • Clean microfiber cloths
  • Isopropyl alcohol (90%+ recommended)
  • Soft brush or old toothbrush
  • Degreaser (bike-specific or mild)
  • Light lubricant (non-silicone, Teflon-based recommended)
  • Nitrile gloves (optional)

Recommended Cleaning Frequency

For most road cyclists, a monthly cleaning schedule is sufficient under dry conditions. However, if you regularly ride in wet weather, on dirty roads, or in hilly terrain where braking is frequent, a biweekly or even weekly inspection and cleaning may be required.

Step-by-Step Cleaning Procedure

Surface Debris Removal

Begin by inspecting the caliper arms, mounting bolts, and pivot points. Use a dry brush to remove any loose grit or buildup. Pay close attention to the area between the arms, where fine road grime often accumulates unnoticed.

Degrease the Brake Caliper

Using a bike-specific degreaser or isopropyl alcohol, dampen a cloth and wipe down the caliper arms, barrel adjusters, and visible springs. Do not spray degreaser directly onto the brakes as overspray may affect pads or rims. Focus on the pivot joints and the underside of the caliper where contaminants settle.

Brake Pad Inspection and Cleaning

Remove the brake pads by loosening their mounting bolts. Examine them for embedded grit, glazing, or uneven wear. Clean each pad with isopropyl alcohol and a clean cloth. If needed, lightly sand the pad surface with fine-grit sandpaper to remove glazing. Never use oil-based products on brake pads, as this will ruin their friction properties.

Rim Surface Cleaning

Before reinstalling the pads, wipe the braking surface of the rim using alcohol. This removes rubber residue and ensures optimal pad-rim contact. Check for wear indicators on the rim—excessive wear can affect braking and should be addressed separately.

Proper Lubrication of the BR-6700 Calipers

Targeted Lubrication Points

The BR-6700 caliper has several pivot points that benefit from lubrication. Apply a single drop of light lubricant to each pivot—specifically where the arms rotate. Also, apply a small amount to the return spring housing, but be cautious not to over-lubricate, as excess oil can attract dirt.

Do not lubricate:

  • Brake pads
  • Brake tracks on the rims
  • Mounting bolts
  • Adjustment barrels

Work the Lubricant In

Once applied, manually squeeze the calipers a few times to distribute the lubricant evenly. Wipe away any excess with a clean cloth to prevent dust attraction. The movement should become noticeably smoother after this step.

Maintenance Tips for Long-Term Performance

  • Use clean gloves when handling pads or rims to prevent contamination.
  • Avoid harsh household degreasers, which can damage anodized caliper finishes.
  • Store the bike indoors when possible, reducing exposure to moisture.
  • Use a torque wrench [paid link] when reinstalling calipers after deep cleaning to ensure consistent alignment and safety.

When to Replace Instead of Clean

Routine maintenance will extend the lifespan of your BR-6700 brakes, but some signs indicate it’s time for replacement:

  • Worn brake pads showing less than 1mm of compound.
  • Sticky caliper arms that remain sluggish after lubrication.
  • Visible corrosion or pitting at pivot joints or springs.
  • Cracked or deformed parts, particularly in the brake pad holders or caliper arms.

Benefits of a Routine Cleaning and Lubrication Schedule

A consistent maintenance routine ensures your BR-6700 brakes:

  • Deliver smoother, more predictable braking performance.
  • Reduce premature wear on pads and rims.
  • Resist corrosion and mechanical failure.
  • Operate quietly with reduced vibration or squeal.
  • Maintain aesthetic appeal and function, even after years of use.

FAQs About BR-6700 Brake Cleaning and Lubrication

1. Can I use WD-40 on my BR-6700 brakes?
No. WD-40 is not a suitable lubricant for bike brakes and may contaminate pads or braking surfaces.

2. How often should I replace the brake pads?
Inspect monthly. Replace when the groove indicators disappear or if braking power significantly drops despite cleaning.

3. Should I remove the caliper for deep cleaning?
Not always necessary, but periodic removal (every 6 months) allows better access to internal pivots and mounting areas.

4. Is it okay to pressure wash my brakes?
Avoid it. High-pressure water can force debris into pivot points and strip out lubricant.

5. What type of lube works best for caliper pivots?
Use a light, Teflon-based lubricant. Avoid thick grease or oils that attract dirt.

6. Do I need to clean after every wet ride?
Yes. Wet roads cause faster dirt buildup and corrosion risk. Always dry and clean the calipers afterward.
