Upgrade to a 12" OEM Big Brake Kit - Submitted by yamaha Tools needed: Jack Jack Stands Air/Hand Tools Brake Bleeder Kit Cup Rubber Mallet Parts needed: Two 12Ó rotors Two KDM XG350 Calipers Front Brake Pads 1. Jack up the car and place jack stands in the appropriate place so the car rests securely on the stands. 2. Remove four lugnuts holding the wheel in place. Remove wheel. 3. Remove bolts holding caliper on to hub. Also remove bolt holding brake line on. You will get some drainage from the master cylinder. Get a cup or can to hold the fluid which can be used later if so desired. 4. Remove front rotors. You may come across some rust and general sticky rotors when trying to remove the rotor from the hub. GENTLY tap with a rubber mallet until it comes loose. They will eventually come loose it might just take some time. 5. Place the new rotor on hub. You will find that the rotors are cut from the five lug KDM XG350 rotor. The 4x114.3 bolt pattern is perfect, just a tight fit. If need be, hit rotor with a rubber mallet to get rotor onto hub the whole way. 6. Take the correct XG350 caliper and bolt to the Hub. You can use the same bolts from what held on the old caliper. Also attach brake line to the XG350 caliper with the appropriate bolt. 7. After making sure all the bolts are tightened properly it is time to bleed the brakes. This is rather easy to do if you have the right tools. Hook up the brake bleeding kit and be sure to fill the master cylinder with fluid before attempting this. Follow the directions on the box for the bleeder kit or until there are no bubbles coming out of the line. Tighten bleeder on the caliper after this is done. Success! After bleeding the brakes you are done. Sit back and enjoy your new mod. To ensure proper break in of the brake, do a few 25mph-0 stops, and then gently drive the car with the brakes for the first 100 miles to ensure proper break in.
