ACDelco Silicone Brake Lubricant 8 oz (GM OE 10-4019) PTFE‑fortified, water‑resistant

ACDelco Silicone Brake Lubricant (GM OE 10-4019 / 88862182) is an 8‑oz PTFE‑fortified silicone compound designed to reduce brake noise, resist moisture and corrosion, and protect rubber and plastic brake parts. ACDelco engineered this silicone-based brake lubricant to combine the temperature and water resistance of silicone oils with high PTFE loading for superior lubrication and reduced friction. The formula is intended for sliding contact points in drum and disc brake systems where sticking, squeal, or corrosion can cause poor performance or noise. It is compatible with most rubber and plastic brake components, making it a versatile maintenance product for professional technicians and DIYers.

Where should I apply this brake lubricant?

Use this lubricant at contact and sliding points where metal or rubber parts meet and movement occurs. Avoid applying to friction surfaces like pad or rotor faces.

• Slide pins and guide bolts — ensures smooth caliper movement.
• Backing plate contact points — reduces pad rattle and vibration.
• Parking brake levers and drum anchor points — resists moisture and corrosion.
• Rubber boots and bushings — compatible with most compounds for protection and flexibility.

How does the PTFE in this silicone formula help my brakes?

PTFE particles lower surface friction and reduce stick‑slip behavior, which in turn diminishes squeals and vibration-related noises. The combination with silicone oils provides long-lasting lubrication even under heat and wet conditions.

• Reduces friction at contact points for smoother operation.
• Limits stick‑slip that causes intermittent noise.
• Maintains lubricity across a wide temperature range.
• Resists washout from water and road spray for lasting protection.

Is this lubricant safe for rubber and plastic brake parts?

Yes — the ACDelco formula is designed for compatibility with most rubber and plastic compounds used in brake systems. It protects seals and boots while preserving flexibility without swelling or degrading common materials.

• Tested for compatibility with typical brake elastomers and plastics.
• Helps preserve seal integrity and movement of rubber boots.
• Non‑corrosive to metal components when used as directed.
• Not for use on pad friction surfaces or rotors.

How long will one 8‑oz can last in maintenance use?

Longevity depends on frequency of service and number of vehicles, but an 8‑oz can typically covers multiple caliper services on passenger vehicles. Apply sparingly to contact points for efficient use.

• Small, targeted application reduces waste.
• Suitable for several repairs for typical cars and light trucks.
• Store sealed to prevent contamination and extend shelf life.
• Use with appropriate applicator or brush for precise placement.

This lubricant is intended for automotive technicians, maintenance professionals, and informed DIYers who want a reliable, OE‑spec product for brake hardware lubrication. It’s especially useful when addressing brake noise, corroded guide pins, or stiff parking brake linkages. Keep it on hand for routine brake jobs and seasonal service to maintain smooth operation and reduce unwanted brake vibration and rattle.

FAQ

Q: Can I use this on brake pads or rotors?

A: No. Do not apply to friction surfaces like pads or rotors; use only on sliding contacts, pins, and hardware.

Q: Is this safe for rubber brake boots and seals?

A: Yes. The formula is compatible with most rubber and plastic compounds and helps preserve flexibility.
