Mislim da je jako dobro imati diskusiju iz koje se moze sta nauciti i izvuci korisno - za mene je novo sto sam saznao za razliku u specifikaciji izmedju DOT 3/4/5 i jos par detalja za koje nisam prije imao prilike saznati.
(Dodushe, bilo bi ljepshe kada bi se iz diskusije izbacio "nacionalni sport" omalovazavanja (vrlo blago receno) onoga ko ima (malo) drugacije (nedaj Boze suprotno) misljenje/znanje/iskustvo. )
Prvo auto koje smo imali (mali Daihatsu), dosao je nov, bio sa nama oko 12 godina i presao izuzetnih 400 000 kms (zamijenio sam motor na oko 200 000). Nisam "ciljao" da napravim ovu kilometrazu ali sticajem okolnosti tako ispalo.
Nakon prvih 20-30K sam zamijenio tecnost za kocnice i NIKADA vishe. Diskove sam mijenjao cini mi se svakih 80 000. Nikada nije nigdje curilo ili bilo koji drugi kvar a svake godine auto je prosao kroz sljedeci test kocnica prilikom registracije:

This is the ruling for brakes by the RTA.
Safety Check Standards
Brakes Rule 101
Light Vehicles Rules for Authorised Inspection Stations Nov 2005
101.01 Check the operation of the brake controls
Reasons for rejection
a) on rubber faced brake pedals, any metal is showing;
b) on metal brake pedals, there is no anti-slip surface;
c) missing or broken brake pedal or handle;
d) when the service brakes are firmly applied, less than 20% of the pedal travel remains;
e) when steady pressure is applied to the service brake pedal for 10 seconds, the pedal travels towards the floor;
f) where ADR 31 or 35 applies, the brake failure warning light does not operate when the ignition is turned on, and the engine is either not running or the starter motor is engaged;
g) the parking brake ratchet or locking device is not holding the parking brake lever in its applied position.
h) (if fitted with ABS), the ABS self test/failure warning lamp does not operate when the ignition is turned on, and the engine is either not running or the starter motor is engaged;
i) the ABS or brake fail warning lamp remains on when the engine is running or comes on when the brake is applied (with the engine running);
101.02 Inspect the condition of visible brake components.
NOTE: This includes the area underneath the vehicle.
Brakes Rule 101 Light Vehicles Rules for Authorised Inspection Stations Nov 2005
Reason for rejection
a) where visible, any brake component is leaking or is not securely mounted
b) any hydraulic brake hose where, if when the brake pedal is held depressed, the intermediate reinforcement fabric of the hose is exposed or the hose swells or bulges.
NOTE: Cracked or split outer casing on the hose is not reason for rejection.
101.03 Service brake test with a decelerometer
NOTE: i) Decelerometer standards should be read in conjunction with the equipment specifications in Appendix B1 and the equipment manufacturer's specification.
ii) On some vehicles with light axle loads, or when testing in wet weather, it might be difficult to obtain a brake test result because of wheel lockup. In these cases the pedal pressure should be reduced to a point where only the minimum specified deceleration rates are achieved.
Set up a suitable decelerometer in the vehicle cabin. With the vehicle unladen, drive it to at least 30 km/h. Put the transmission into neutral. With both hands on the steering wheel, bring the vehicle to a halt as rapidly as possible in a safe manner with one sustained and smooth braking action using the service brakes.
Reasons for rejection
a) the application of the brakes causes the vehicle to swerve from a straight line path;
b) the service braking system decelerates the vehicle at less than the performance requirement specified in Table 1 or 1a.
-------------------------------
Nikada kocnice nisu pale na ovom testu - a ako je ovlasteni servis zadovoljan sa tim onda sam i ja.
Hocemo li mozda onih preostalih predjenih 380 000 km (plus jos ostala poprilicna kilometraza na par drugih auta) pripisati "da smo imali srecu" da izbjegnemo stabla i bandere.
Ostajem pri misljenju da je riskantnije mijenjati tecnost za kocnice u pokusaju da se podigne nivo kljucanja sa nekih 200 C
na normalnih 240 C
!
Sam cin praznjenja i odvrtanja/zavrtanja crijeva i sarafa je dovoljan rizik da totalno ponisti svu mogucu korist koja se dobija zamjenom tecnosti za kocnice.
