9310

This is it, the #1 adapter set for your shop !!!
 

$559.00

THE MOST COMPLETE ADAPTER SET... CUT ALL TYPES OF ROTORS, INCLUDING COMPOSITE!

Buyer Beware!
GWR urges you to compare before you buy, this is the only OEM 14 piece kit.

(Note: Most internet sellers only offer a 13 piece kit, it's missing one of the master backing plates)

This set is the must have for every brake lathe. It has 1" hole for most arbors and fits all style rotors (std, composite, etc). The secret to perfect rotor cut is adding 30lbs to the rotor's mass and this system is the only one that does just that... for a guaranteed 10% smoother cut!
The only adapters guaranteed to smooth surface finishes and eliminate bad cuts, with the fastest set up time in the industry. These adapters are the system recommended by more OEM's (Ammco, Rels, FMC, Hunter, etc) because you add 20 to 30 pounds to the rotor mass (weight), plus they allow 360º rotor contact. We can easily save you up to 50% on this item, don't spend $100's more for the same adapter set. (Six precisely machined centering cones span the range of 1.84" to 3.85" hub holes)

 Our adapters are the design Ammco and other OE Manufactures have used in their new lathe machines for nearly 20 years. They are the best, the original and they eliminate all the wasted time and money required to use other style adapters.


If you cut larger rotors and possibly those on trucks, add the 9313 set below for complete coverage.
P.S. Be sure to ask about special combo promotion and freight offer, when purchasing both.

$24.95

Extreme Duty 4-Spring Silencer Band System. Each spring is packed with a dense Neoprene rod to accept maximum vibrations and harmonics. This is the best silencer on the planet! Throw out that old style rubber band with lead weights, they actually create an out of balance condition that produces higher final finish roughness numbers.
(Just try this little experiment if you think there is no reason to switch. Grab a rotor, slap it on a lathe and the wrap your rubber band silencer with lead weights around it, as you normally do. Now look at the rotor from a side view and focus on the part of the rubber silencer band that over laps. Notice that there is rubber overlapping but more importantly, but of most importance is the extra lead in this area. Simple physics will tell you your rotor is now out of balance! It will spin with a distorted harmonic energy, a vibration that will transfer into every cut you make. This is a built in flaw in the design and the only way to eliminate it is to use our symmetrically balanced 4-Spring Silencer.)

Extra Bonus.... Our metal silencers last 4 to 5 times longer that rubber ones!

Our ROTOR HONES Produce Perfect Cross-Hatch Patterns!

Flexible surface hones for rotors utilize high tech patented technology to produce the ideal surface finish on automotive and motorcycle disc brake rotors, automotive fly wheels and clutch plates. Sandpaper, scotch pads, swirl discs, grinding pads or the like all damage the surface because they are following your hands motion, this creates microscopic dips and grooves in the rotor. Remember, this is the rotor you just spent 10 minutes cutting, trying to create a straight, parallel surface with .001" tolerances.

Here is the bottom line... You must apply a Cross-Hatched finish to the rotor that approaches the required 40 to 42 Ra final surface. Note that this is not the Non-Directional one you have been taught is right, when someone says Non-Directional they are misunderstanding the metal machining process for cast iron. Compare the finish on a engine's cylinder wall, after it's re-bored and before you put in new pistons. Would you ever think of using a piece of sandpaper or scotch pad to scratch up the walls to create a proper break-in finish?

This design is a multiple Undercar Digest "Top Ten" tool winner!

The tools lasted for over 200 sets of rotors, our testing indicated this tool is a great idea;
it's cheaper to use over a long period of time than other ideas that are on the market.
Rob Jones Assistant Manager / Midas Muffler

The net cost per rotor is 1/2 that of pads, discs, sandpaper etc, because you need to change them on every single rotor if you don't want to have different finishes on the same vehicle. That can't be good! Throw out your old sandpaper on a block and get the job done better and more efficiently. Get more rotors per hone than any abrasive system, proper Ra surface finish every usage and a true crosshatch in just seconds...

What are you waiting for? You'll never go back after trying one of these tools!

DIAL INDICATOR W/ MAGNETIC BASE
EVERY SHOP DOING BRAKES "MUST" HAVE THIS TOOL!
This is the item we talk about in every seminars we do... to check rotors you must have equipment that can measure run out (warpage) both on the vehicle and on the lathe. Simply mount the magnet base on a steel surface (lathe or caliper mounting area) and point the indicator to the surface you want to check.. Then adjust the dial bezel to zero and finally rotate the object to determine if it meets specifications. You will save countless hours of wasted time by spending just 30 seconds checking each rotor. Easily determine if you have a bend hub, spindle or hat without having to cut a rotor first... a savings of 10 to 15 minutes at least!

 

Safely and easily stop the flow of water to or from a radiator
or smaller heater hoses, to check for leaks and more.
Stop putting contaminated brake fluid back in to the master cylinder!
One handed operation makes this tool a snap to use, simply slide it over the rubber hose and pull down on the ring around the handles. By design the jaws won't completely close so you can't damage the hose, unlike other high priced locking tools on the market. This is an approved and safe tool, everyone needs!
