Front Brake Disc.
« on: December 08, 2016, 01:41:22 AM »
Hi guys,

Soon it will be due to replace my front brake disc. 

After searching high and low, I discovered that demon tweeks is having a clearance sale on the EBC Vee-Rotor discs. Worth a look as I can vouch that it's really well priced now.

Here is the link:
http://www.demon-tweeks.co.uk/motorcycle/brake-discs/bike/kymco/2013/downtown-200i/ebc-brakes-vee-rotor-wave-disc-black-center-front

The description:
The Vee-Rotor from EBC Brakes is the latest addition to their ever growing brake rotor selection. This new eye-catching design has been developed in line with the on-going trend of riders customising/personalising their machine, rather than simply just replacing parts like for like. The ‘Vee-Rotor’ features an aggressively styled ‘wavy’design, with radical new machining techniques making for EBC’s lightest weight rotor profile. Their fully floating design features EBC’s unique and patented S-Drive button system, which use square sided rivets captured in square drive pockets on the rotor and hub allowing the outer rotor the ability to expand and contract freely under the heat of braking without suffering rivet lock – preventing distortion and vibration. EBC have also developed a range of solid rear discs, made from heat treated stainless steel with the same outer rotor design to fully compliment the front rotors.
Of course I have ordered mine.

Good Luck!

Morning,

My EBC VR rotor arrived in the mail.

Looks the business. The manufacturer claims they are full floating.

From experience, in the past full floating didn't that a spring washer at the buttons, so perhaps this is new/current technology?

Yep, pretty cool. I have one of those, too. Bought it at a yard sale.

More importantly: is that your bank statement under the disc?
If you're in Mexico ...that could be receipt for a pair of new NGKs. Just under $5 American.
 If you're in the U.K. - that is ....impressive.

Finally got around to get my new front rotor mounted. Of course new pads as well. Factory fitted rotor already at 2.52mm, which is way below the recommended min 3mm.

1) remove front wheel
2) remove front rotor and speed pickup disc
3) cleaned spindle and wheel spacers and lubed with silicon lubricant
4) mount on new rotor and speed pickup disc, threadlocker on bolts
5) removed old pads, cleaned caliper and lubed brake pad position bolt
6) installed front wheel
7) installed front pads
8) test ride

As you can see at 47,600km, the original rotor is heavily worn.

Well, if you attend superbike school, the instructor will ask for you to round ride the track without using your brakes which forces you to 'read' the road and adjust your speed accordingly.
