Dynapro Dust-Boot

TheDynapro Dust-Boot (DP-DB) model of the Dynapro lug mountcaliper was developed for applications that require or prefer a dust-booted piston. Dust-booted aluminum pistons provide added protection against road or track born dirt and debris on low to intermediate temperature rangeapplications that may also operate in harsh environments.The pistons are clear anodizedto eliminate corrosion while providing added lubricity for drag-free operation within thebores. The dust boots work in conjunction with high-temperature square faced internal seals in the caliper bores to provide optimum performance, ultimate reliability, and quick turn around at pad service intervals.

The strength of the DynaPro is a combination of process and design. The DynaPro is stress-flow forged from premium grade billet. Stress-flow forging realigns the grain structure of the metal within the contour of the body design. This process produces a part with superior strength over parts simply machined from straight grainedblocks of billet. The FEA generated body design incorporates a highly fortified radial transition that eliminates steps and shoulders between the piston housings and the bridges. Incorporating a radius in thiscritical area substantially increases resistance to deflection and caliper body separation under load. Structural deflection and volume displacement testing have proven the efficiency of this innovative design. Reductions in overall deflection, and the subsequentdecreases in fluid volume displacement, translate to increased clamping efficiency with less pedal travel. The bottom line is a firm, responsive pedal with outstanding stopping power.

The DynaPro is loaded with other enhancementsfor performance and durability. The calipers feature Quick-E-Clip pad retainers that support a 7812 type brake pad from the top. Not only does it allow for fast pad service without caliper removal, the bottom pad supports have been removedto create a slimmer profile that can be more easily fittedinto tight clearance applications. An optional bridge bolt kit, P/N 230-10188is also available to provide additional body strength and fortified pad retention in thecenter of the caliper bridge for extreme high pressure, high load applications.

Love these treats!
Flavor Name: Peanut Butter with Cranberry
We love these dog treats! I have a large a small dog, both can safely eat them. They are softer, but firm. No teeth breaking as both of my dogs are seniors. I really like that they are made with natural ingredients, are made in the USA, and contain no rawhide. Im a frequent buyer of these treats.

Excellent Option with No Chicken products in it.My Dogs Love Them!!!!!
Flavor Name: Peanut Butter with Cranberry
My dogs absolutely love these bones. I have 4 standard goldendoodles who are very sensitive to chicken. So many dog products have chicken or chicken by products like chicken meal. With these bones I don’t have to worry about that. Even though they are fairly expensive, I continue to get them because my dogs love them and are not allergic to any of the ingredients. Great Product
