A replacement part arrived as TOYOTA genuine frontal disc bake pad yesterday, I'm going to do that with some combination work, replacement of brake fluid and overhaul of brake caliper including rear ones. Though it was done by some dealer as a periodical service treatment, I do not always believe in their way, for example, loosening and tightening caliper fixing bolts. As the brake system is an indispensable safety one, I wanna ascertain by myself, if I continue. Judging from my experiences, piston boots and sealing rubber packing are not always necessary to be replaced into new parts, just some removal of vanish deposit generated hard material covering piston surface is the task. Smooth and good brake pedal touch would be obtained after this kind of treatment. Though brake pad remains 3mm thickness more, now is the time to be replaced, because too much projection of piston from the cylinder invites squeezing leading to some worse pedal touch and oval wear of cylinder surface. Braking effect is mainly dictated by the diameter of brake disk wheel, the pad area had been increased comparing with the same 14" wheel's one equipped in former model, EP82 Starlet, so not compatible. Though much inexpensive parts supply from some third party exists, I dare have chosen TOYOTA genuine parts. The transient of braking stage is important for me and the quality of the pad materials are fixed by the factory after some adequate experiments, this is why I insist on genuine parts especially for important portions.
Magnet clutch part and brushes in the alternator would last it covers 150,000km use, so more 90,000km would be lasted except V-shape belts, remember 2NZ-FE motor do have chain driven mechanism as a timing belt. Oils & water periodical replacement in future would be the key to continue NCP10 Vitz long from now.
