Raybestos RPT Rotors

Raybestos® Rust Prevention Technology (RPT™) Coated Rotors

Judge this Rotor by its Cover

Open-wheel designs on modern vehicles leave brake parts, particularly rotors, more exposed to the elements. If a rotor is uncoated, corrosion and red rust begin to form immediately.

Raybestos Rust Prevention Technology (RPT) coated rotors use a propriety finishing technology to coat each rotor’s entire surface, including the cooling vanes. The full Grey Fusion 4.0™ coating helps resist corrosion and significantly delays rust-induced performance issues.

The Raybestos RPT rotor is ideal for drivers in rust-prone areas, including:

• The rust belt, where aggressive snow and ice melt chemicals accelerate the corrosion of rotors
• Coastal regions with salt in the air and high humidity

RPT rotors are built to endure the harshest of weather conditions and deliver:

• Best-in-class performance
• Ultra-smooth braking
• Maximized friction life

At Least It Was Entertaining

Yesterday afternoon saw plenty of action on Roland St. right in front of our door. At about 1pm one of the Cat excavators working on the road construction was crawling back near our entrance and grabbed a string of wires that cross from the side of our building to a hydro pole across the street.

Within 30 minutes a swarm of orange-clad hydro workers was snapping pictures and taking notes. A police cruiser arrived to question the operator. A landscaper was called to cut and chip a tree that had grown around the base of the pole. A commercial electric boom truck secured the pole and several hydro boom trucks sat waiting.

Hours passed, the tree disappeared, more trucks arrived. A Tbaytel worker advised us that the pole had been snapped and would be replaced overnight. Somehow we still had power, phones and internet.

This project is off to a rough start, to say the least. Last week they dug up a gas line. For the time being our entrance is accessible again and hopefully, there are no more entertaining days.

Bad Day on the Line

Here's a special part we received this morning. Must have been made early on a Monday or late on a Friday.

New Useful Link

BBB Industries has just introduced an online database of wiring diagrams and Technical Service Bulletins which are useful for searching out problems. These bulletins are created by the vehicle manufacturers and can answer many questions that are often only available through a dealer or paid subscription. Check it out under our Useful Links.

Rotor Specs

We get asked for rotor spec books on a weekly basis. Used to be, brake manufacturers would publish a new book every other year or so and hand them out free of charge. Used to be, rotors were a major purchase. These days rotors are fairly inexpensive and manufacturers don't hand out much of anything without a price tag.

The quickest way to get specs for your car or truck is to use an online catalog like the Raybestos brake catalog. Click in the year, make and model and then select front or rear rotor. A final click on the part number will bring up a new window with a variety of specs including the minimum thickness. You'll need a decent micrometer to measure your existing rotor to decide whether they can be saved by machining. With most new rotors being lighter and therefore thinner there is not much leeway. Thickness is just one aspect. If they are close to the limit and have a vibration or wobble you will surely need new steel. Machining material from a rotor that is warped will lead to further warping as there is less mass to fight off the forces that heat applies to the rotor.
