Permatex Ultra Disc Brake Caliper Lube 8 oz — Synthetic High-Temp, Water-Resistant

Permatex Ultra Disc Brake Caliper Lube is a green, 100% synthetic, nonmelting lubricant designed to protect caliper pins, hardware and the backside of brake pads under extreme temperatures and heavy use.

When brakes run hot, ordinary greases can melt or wash away, which leads to sticking, uneven pad wear and noisy operation. Permatex 24110 addresses those risks with a synthetic formula engineered to stay in place from -40°F to 400°F (-40°C to 204°C). It’s formulated for automotive disc brake systems and applied to the metal-to-metal contact points that must remain free and smooth for reliable braking performance and longer pad life.

How does this lubricant prevent caliper sticking and seizing?

The Ultra Disc Brake Caliper Lube forms a stable film that resists breakdown at high temperatures and under wet conditions, reducing friction and corrosion at sliding surfaces. By maintaining lubrication across service intervals, it helps brake components move freely and reduces the chance of pad drag or uneven wear.

• High-temperature stability up to 400°F (204°C) for sustained performance
• Nonmelting synthetic base that resists washout and hardening
• Protects metal contact areas against corrosion and galling

Where should I apply this lubricant on my disc brake assembly?

Use this grease on caliper guide pins, slide hardware, shims and the back side of brake pads where metal-to-metal contact occurs. Applying a thin, even coat on these points helps the caliper operate smoothly and prevents noise from pad-to-caliper contact.

• Caliper pins and slide bolts — ensure full travel and alignment
• Mounting hardware and anti-rattle clips — reduce vibration and noise
• Back side of brake pads — cushion metal-to-metal contact and limit squeal

Will this lube hold up in wet or cold climates?

Yes. The formula's low-temperature fluidity keeps components lubricated down to -40°F (-40°C), and its synthetic makeup resists being washed away by water or road splash. That combination makes it suitable for year-round use in harsh weather and for vehicles exposed to salt and moisture.

• Operates effectively in freezing temperatures down to -40°F
• Water-resistant formulation reduces washout during rain or slush
• Helps prevent corrosion in salty or humid environments

How does using this product affect brake pad life and performance?

Proper lubrication of contact points reduces uneven wear and heat-related sticking, which can extend pad service life and preserve braking consistency. While it won’t change pad compound wear characteristics, it minimizes secondary causes of premature replacement such as seized pins or pad drag.

• Promotes even pad movement to avoid localized overheating
• Reduces noise by damping metal-to-metal contact
• Maintains smooth caliper action for consistent pedal feel

Who is this for: Permatex Ultra Disc Brake Caliper Lube is aimed at DIY mechanics, professional technicians and fleet maintenance teams who need a durable, high-temperature synthetic grease for disc brake upkeep. It’s suitable for passenger cars, light trucks and SUVs where caliper sliding parts and pad backs require reliable lubrication to reduce noise, prevent sticking and support predictable braking behavior.
