The torque specifications for the light-duty package are 130 ft./lbs. for the front caliper brackets and 120 ft./lbs. for the rear caliper brackets. The heavy-duty front brake caliper bracket has a torque specification of 275 ft./lbs.

For the 2017 Ram 1500, the bolt torque specifications for the caliper bracket typically range from 125 to 150 foot-pounds (ft-lbs), depending on the specific model and configuration. It’s important to consult the vehicle’s service manual or contact a certified Ram dealership to confirm the exact torque specifications for your particular model.

Proper torque application is crucial to ensure that the caliper bracket bolts are securely tightened, maintaining the integrity and functionality of the braking system. Under-tightening can lead to loose bolts and potential brake caliper misalignment, while over-tightening may risk damaging the bolts or the bracket itself.

Do you need Loctite on caliper bracket bolts?

Generally threadlocker is not called for on caliper bracket bolts as the proper torque will hold them securely. But if you want to use it, I would not use anything but “blue”.

“Applying Loctite to caliper bracket bolts is a topic that sparks debate among automotive enthusiasts and professionals alike. Loctite is a brand of threadlocker adhesive designed to prevent bolts from loosening due to vibration or thermal expansion. While some argue that using Loctite on caliper bracket bolts adds an extra layer of security, others caution against its indiscriminate use.

In many cases, caliper bracket bolts are designed to be secured without the need for threadlocker, as they rely on proper torque specifications and hardware design to maintain tightness. Additionally, using Loctite on these bolts may make future removal and maintenance more difficult, potentially leading to damaged threads or stripped bolts.

Are caliper bracket bolts reverse threaded?

Nope, highly doubt that’s ever been used. Reverse threading is used when normal rotation of the part would tend to loosen fasteners. So they sometimes show up on pulley and idler bolts, lug nuts, etc. There’s no possible benefit on a non-spinning part like calipers.

Caliper bracket bolts are not typically reverse threaded. In most cases, they follow the standard right-hand thread orientation, meaning they tighten clockwise and loosen counterclockwise. This conventional threading allows for intuitive and consistent tightening and loosening procedures during brake maintenance or repair.

However, it’s essential to note that there can be exceptions, especially in specialized or unique vehicle models. Always refer to the specific vehicle’s service manual or manufacturer guidelines for accurate information regarding the threading direction of caliper bracket bolts.

Regardless of the threading direction, proper torque specifications must be followed when tightening caliper bracket bolts to ensure the safety and effectiveness of the braking system. Overlooking torque specifications or incorrectly threading the bolts can lead to brake caliper misalignment, uneven brake pad wear, or compromised braking performance, posing significant risks to vehicle operation and safety.

Should brake caliper bolts be greased?

The sliding pins of a caliper system need lubed. Mosy common “grease” is not a good choice, as “grease” attracts brake dust into itself, and then tends to bind, instead of lube. A dry lubricate is usually used to decrease dust accumulation.

“Greasing brake caliper bolts can be beneficial for smooth operation and longevity of the braking system. Applying a thin layer of high-temperature brake grease to the threads and contact surfaces of the caliper bolts can help prevent corrosion, reduce friction, and inhibit the formation of rust, which can make future brake maintenance easier.

However, it’s essential to exercise caution and apply grease sparingly, avoiding excessive amounts that could contaminate brake components or interfere with braking performance. Additionally, it’s crucial to use a grease specifically formulated for high-temperature applications, as regular grease may not withstand the heat generated during braking and could lead to brake fade or failure.

Before greasing caliper bolts, always consult your vehicle’s service manual or manufacturer recommendations to ensure compatibility and proper application. By greasing brake caliper bolts correctly, you can contribute to smoother brake operation, enhanced longevity, and improved overall braking performance.”
