I have 09 Tacoma. Their OEM pads are great for stopping power, but they leave a dark residue on the wheel cover. Any of you gentlemen have any suggs?
I typically get 4o,000 plus out of a set of OEM pads. Like I said, they stop good, and they're easy on the rotors.
Thanks in advance.

I have been a mechanic for many years. I used to buy Napa Auto Parts almost always. I felt the parts were good quality, although more expensive than others. It does not pay to install poor quality parts on a car, they come back, and bite you! Unfortunately, a few years ago it seems Napa changed their policy on quality. This happened around the time they totally changed the on-line site. Around the same time, I started looking at Rock Auto on-line. Rock Auto offers each part by a few different manufacturers, quality levels, and prices. I started noticing that despite Napa still charging higher prices, they were now supplying the cheapest, lowest quality parts instead of the better quality they were known for. Given that, why would a person order from Napa, when Rock Auto is surprisingly lower priced, and you have a quality level choice . Napa seems to be riding on their previous well known name, while keeping the prices artificially high.
Some prime examples of this is, I purchased a starter solenoid, (eckland, Napa's electrical brand), as a preventative measure. The third start-up, after installing, the solenoid froze in the on position, with key off, and kept the starter spinning and engaged until I could unhook one battery terminal. Burned up the relay, starter, and a couple wires. I purchased a rebuilt alternator, took it from the box, and turned it, it felt rough turning, as if there was dirt in the bearing race or defective bearing components. I purchased Napa's best fuel pump, and it was very noisy from day one. I purchased a set of Napa Branded, 2 ton each, jack stands. One of them had a defective casting that would not allow the stop to lock in place. Although it seemed it locked, when weight was applied, it fell. I purchased rebuilt Ford Front calipers from Napa, and with in one year, the unplated soft steel bleeder screws has rusted solid to the caliper!
Are other people seeing this too??

OEM vs. Aftermarket Parts for Your Car: How to Choose
APF posted a topic in General Auto Parts Discussion,
When selecting parts for a car repair, it pays to know the differences between original and aftermarket parts. Whenever possible, get estimates for both.
Choosing between original and aftermarket car parts — and even used parts of either type — is all about squaring your priorities with your budget.
You’ll have different options depending on the part and the shop. And the best choice will depend on whether you’re trying to keep repairs cheap, restore your car’s appearance after a wreck or soup up your ride.
Original equipment manufacturer (OEM) parts match those that came with your car, and are of the same quality as its original parts. They’re also the most expensive.-

Replacement Intervals For Oil And Air Filters In Today’s Vehicles
APF posted a topic in Automotive Wipers, Filters, Oil & Lubricants,
The factory-recommended replacement intervals for filters can vary quite a bit depending on the year, make and model of the vehicle, as well as how it is driven. As a rule, older vehicles (those more than 15 to 20 years old) typically have more frequent service intervals than newer vehicles. Why? Because late-model vehicles require less maintenance, thanks to improvements in motor oils, transmission fluids, engine design and filter media.
Many long-life air and oil filters use synthetic fiber media or a blend of cellulose and synthetic fibers to extend filter life.
Changing the oil and filter every 3,000 miles was standard practice decades ago. But it’s no longer necessary because most multi-viscosity oils today are a synthetic blend or a full synthetic that resist viscosity breakdown and oxidation for a much longer period of time. Late-model fuel-injected engines also run much cleaner than their carbureted ancestors, which reduces oil contamination in the crankcase.-

The materials used in making molds are called molding materials. The sand molds are mainly molded sand and core sand, which are composed of sand, binder and additives.
1.Molding materials should have the following properties:
（1）Plasticity: molding sand and core sand are easy to form under the action of external forces.
（2）Sufficient strength: molding sand and core sand are not easy to destroy under external force.
（3）Fire resistance: molding sand and core sand are difficult to soften, sinter and adhere at high temperature.
（4）Permeability: molding sand and core sand must be easy to ventilate after compacting.
（5）Concession: molding sand and core sand can be compressed when cooled.
2.Pattern and core box
The pattern and core box are tools for making moulds and cores.
The shape of a casting to form a shape equivalent to the external shape of the casting. The core forms the inner cavity shape of the casting, and the core box is the tool for making the core.
Sand moulds and core boxes are used for multi-purpose wood casting. Metal mold, plastic mold and other patterns for special casting.
3.Modeling method
According to the different methods of modeling operation, it can be divided into:
（1）Manual molding: sand filling, compacting, mold lifting and so on mainly have the manual completion, the operation is flexible, the productivity is low, mainly uses in the single piece small batch production. There are many specific methods of manual modeling: whole mold modeling, three-box modeling, scraper modeling, false box modeling and so on.
（2）Machine Modeling: Mechanization of sand filling, compacting and moulding, high productivity and large investment, mainly used for mass production
4.Technical problems to be solved in sand casting
（1）The choice of pouring position: the main processing surface and large plane of the casting should be facing down, and the part of the Dian wall of the casting should be placed at the bottom.
（2）Selection of parting surface: plane parting surface should be adopted as far as possible, the number of parting surface should be as small as possible, so that all or most of the castings are placed in the same sand mold.
（3）Drawing inclination and casting fillet: In order to start the mold conveniently, the mold should have a certain drawing inclination, the higher the mold, the smaller the slope value: the inner wall inclination is larger than the outer wall inclination. In order to prevent the casting from producing stress and cracks at the wall joints and corners, the casting wall joints and corners should be designed into rounded corners.
