Project Bike: Yamaha Jupiter-Z 2004, TDR Big Brake Disc Upgrade

Brake is always be the most important component of the vehicle. And for me it even more important than the engine, I assume that our safety often rely on this part, the condition of the brake system can determine our fate when driving or riding our vehicle.

That of course also applied to my 2004 Yamaha Jupiter-Z. It is more than 10 years ago since this model was launched by Yamaha Indonesia Motor Manufacturing.

It has air cooled single cylinder 110cc engine with carburetor fuel system and cdi ignition. This bike was so great, it never falls me to ground or break down when I was in the middle of travel to somewhere. Even I did not replacing much part to the newest one or a racing parts, it still under my control, I start it up, it light up, I open the throttle anyway anytime I want, it just accord my intention. 


Start from 2015, I began to make this bike as a refreshment project. Synchronize with my budget I begin to replace the crack rear combination lamp lens, replace the battery, suspensions, re-set the carb and the earlier activity, I replace and upgrade it’s piston and camshaft. But nowadays at my new living place (it’s 500km away from parents town) the braking system seems to tired and gave a little error symptoms. The engine feels heavier, it needs more effort to accelerate, plus I saw the disc brake surface is worn out and the braking pads have different thickness. This problem may caused by many things but I assume the old master piston membrane can make the caliper’s piston hard to release the pressure and the caliper itself is in dirty condition.

Right after I go to Yamaha Indonesia website to check the parts catalogue and note the serial number. Well this is very helpful, the manufacturer gave the customers the valid data of the parts number and even the price and even it available in the app store or google play as an application! Wow! Imagine all the manufacturer give this service to us. Ok then, I order the piston set named master cylinder assy (5LM-F583T-00) to my relative at Yamaha Timuran Motor Solo and also the disc brake, I choose TDR big floating disc to upgrade my braking performance.
