If you want a high-performance lubricant that handles extreme heat and prevents caliper binding on your pickup truck, choose CRC SL3301; if you need the specific rubber seals and dust boots to repair a worn caliper piston on your DB35 model, choose Generic UFP DB35.
• CRC SL3301: Its biggest strength is the advanced synthetic blend of molybdenum, PTFE, and graphite designed for temperatures ranging from -30F to 600F, but it is not VOC compliant in California or other strict jurisdictions. This pick is for mechanics and DIYers who need reliable grease for every brake job without seizing components.
• Generic UFP DB35: Its biggest strength is providing the exact inner and outer diameter seals required for the DB35 caliper model, ensuring a proper fit for one caliper only, though it is strictly a replacement part kit rather than a lubricant. This pick is for owners whose DB35 calipers have failed due to torn boots or hardened seals and require a direct hardware swap.
The CRC SL3301 is engineered as a comprehensive solution for brake maintenance, specifically targeting the mechanical friction points that cause failure over time. What sets this product apart is its formulation. It combines molybdenum, PTFE, and graphite into a single synthetic grease package. This isn't just a generic lubricant; it is designed to operate across an extreme temperature spectrum, staying stable whether you are braking hard after a long descent or dealing with freezing winter mornings. The -30F to 600F range means it won't freeze up in cold weather or melt away under heavy load, which is critical for heavy-duty applications like towing or hauling in a pickup truck.
For anyone performing a brake job, this grease serves a dual purpose. It prevents caliper binding, which often leads to uneven pad wear and pulling issues, and it stops vibration that can make brakes squeal or shudder. Furthermore, its corrosion-resistant properties protect the metal surfaces inside the caliper assembly, extending the life of the components. If you are looking for a product that keeps your brake system moving smoothly and quietly, this synthetic formula is built for that specific outcome.
However, there is a significant regulatory trade-off to consider before buying. This product is not VOC (Volatile Organic Compound) compliant for California and OTC regions. If you live in these areas or plan to work on vehicles registered there, you cannot legally use this specific tube. You would need to find a different grease that meets local environmental standards. It is ideal for the owner who prioritizes performance and thermal stability over regional compliance restrictions.

The Generic UFP DB35 is a precision hardware component, not a fluid or paste. Its entire existence revolves around fitting a specific problem: a damaged caliper piston seal or a torn dust boot on the DB35 caliper model. When a brake caliper leaks fluid or allows moisture and debris to enter the piston area, the result is a spongy pedal, sticking brakes, or complete failure. This kit addresses those mechanical failures directly by replacing the worn-out rubber parts. It includes exactly one seal and one dust boot, designed to service a single caliper.
The specifications here are all about geometry and fitment. The seal has a precise inner diameter of 2.103 inches and an outer diameter of 2.331 inches. These numbers are not suggestions; they are the physical requirements for the DB35 caliper to function correctly. If the dimensions do not match perfectly, the seal will either leak immediately or prevent the piston from sliding back into place. The inclusion of the dust boot (part number 33307) alongside the seal (part number 33004) ensures that once reassembled, the piston is protected from road grime and water. This is essential for maintaining brake performance in harsh driving conditions.
This product is strictly for those who know their vehicle requires a DB35 caliper replacement. There is no ambiguity here: if your caliper model is not DB35, this part will not work. It is also important to verify the caliper model before ordering, as using the wrong seal size can lead to catastrophic brake failure. It is the right choice for a mechanic or DIYer who has diagnosed a specific seal failure and needs the exact replacement hardware to get the job done safely.
• Best for extreme heat resistance → CRC SL3301, thanks to its -30F to 600F operating range.
• Best for preventing caliper binding → CRC SL3301, as its synthetic blend reduces friction between moving metal parts.
• Best for sealing fluid leaks → Generic UFP DB35, because it replaces the physical barrier that holds hydraulic pressure.
• Best for protecting against corrosion → CRC SL3301, which coats metal surfaces to prevent rust during operation.
• Best for restoring piston movement → Generic UFP DB35, which provides the smooth surface needed for the piston to slide within the bore.
• Best for California/O TC compliance → Neither works here for the CRC product; you must skip the CRC SL3301 if you are in these zones.
• Best for a specific caliper model (DB35) → Generic UFP DB35, as it is custom-fitted to those exact dimensions.
• Best for a full brake job preparation → CRC SL3301, since it applies to every brake job regardless of the specific caliper brand.
I recommend choosing the CRC SL3301 if your goal is to maintain your pickup truck's braking system proactively. I would buy this grease because the combination of molybdenum, PTFE, and graphite offers superior protection against the thermal stress and corrosion that trucks face daily. However, if your brake pedal feels spongy or your caliper is leaking, the Generic UFP DB35 is the only logical choice, as no amount of grease can fix a torn rubber seal. Ultimately, for most regular maintenance on a truck, the CRC SL3301 is the tool that keeps everything running smoothly, while the UFP DB35 is the emergency fix for when the hardware itself breaks down.
Yes, the data confirms it operates effectively from -30F to 600F, making it suitable for both freezing winters and hot summer braking sessions.
No, each kit contains one seal and one boot specifically for one caliper. Since most cars have one caliper per wheel, you generally buy one kit per wheel unless you have dual-piston setups.
No, the kit is strictly for the DB35 caliper model with a 2.103" inner diameter. Using it on a different model will likely result in a poor fit and brake failure.
The product is not VOC compliant, which violates California air quality regulations regarding volatile organic compounds, so it is restricted in that state and other OTC regions.
