2019 Porsche Cayenne Diesel First Test
The Porsche Cayenne is the German automaker's best-selling vehicle, and it might be because there's a variant for just about everyone. Whether buyers have the need for speed or want a luxury crossover but are tired of spending too much time at the pump, various Cayenne variants are sure to fit the bill. With the arrival of the oil-burning 2013 Cayenne Diesel, choosing just one gets trickier, but if you're going to make use of the "S" and "U" in SUV, the Diesel is the way to go. Service signs along the highway won't catch the eye of Cayenne Diesel drivers as much those in Cayenne V-6 or S Hybrid models, because goes much farther on one tank. The diesel gets 20/29 mpg city/highway, besting the 16/23 mpg of the Cayenne V-6 and the 20/24 mpg of the Cayenne S Hybrid. Although squiggly roads aren't normally somewhere you'd want to drive an SUV with great fervor, the Cayenne is an exception. The Cayenne Diesel completes the figure eight in 27.1 seconds at an average 0.64 g, and doesn't feel its weight or size when pushed hard on winding roads. 2205 premium for the 18-way adaptive sport seats with memory package our Metallic Green tester had. 3980 air suspension with self-leveling height adjustment and Porsche's Active Suspension Management, which came in handy once the pavement met the dirt. Benson Kong. Off-road mode and hill descent control further prepped the Cayenne for dirt duty, with the switches located on the button-cluttered center driveline tunnel, which looks like something you'd find aboard the Starship Enterprise.
I use a 24mm socket and a flat steel bar to depress the pistons. Once the pistons get moving, they will seat smoothly. Should the pistons stick, and not enter the cylinder, remove and check to make sure the cylinder sealing ring has not slipped from the groove. Install piston dust covers, making sure they are pressed down around the entire lip of the seal area. It should be quite difficult to seat the outer edge of the dust cover. Install caliper o-rings (between caliper halves) as shown. Make sure the adjoining caliper halves are perfectly clean before mating. As you will see, my calipers were beginning to seep fluid as is indicated by the dark areas. This is not surprising as they are more than likely the original calipers and are now over 40 years old. It was only a matter of time before they would start to leak more. DO NOT put any type of sealant on o-rings or between caliper halves.
When joining ATE caliper halves, make sure the o-rings do not move from the recess. If for any reason you suspect the o-rings might have moved, double check before securing the two halves. This entire job boils down to whether or not you come to a proper stop. While holding caliper halves together securely, insert the four bolts, and hand tighten to keep caliper o-rings from moving out of position. Make sure these caliper bolts are free from rust or dirt. These bolts do not require thread lock as indicated by the absence of the product on removal. I simply removed the rust and cleaned up the bolts before reinstallation. Torque the four ATE caliper bolts to 24.5 foot pounds. This step should be done however in two phases, as with most torquing. First is to torque the four bolts to 12 ft. The caliper is now ready to be installed.
Fit new flexible brake line and tighten. Remember to pass the new brake line though the retaining eye on the back side of the wheel, and attach to main brake fluid line. Be sure to also install a new bolt locking tab for the two caliper retaining bolts. It is recommended that new bolts be used. Install brake pads and hardware greased well with appropriate caliper grease. DO NOT get grease on the fronts of the pads or the rotor surface. Bleed brakes. If you use the Speed Bleeder system, follow the manufacturers directions. Make sure the fluid is air free before you stop passing fluid through the system! Take car out on side streets to make sure you are able to stop fully. Brakes will still need to be seated (bedded) according to manufacturer recommendations. 1,000 for all four. In my case this can go toward the many other unexpected expenses on this restoration.
