Merc disc rotor lifespan?

[Fuelsaver]

 

I do a proper inspection of the timing belt when it is removed for replacement but u can peek at it if u remove the timing belt cover.

 

Most other cars hv 2 mileage to change the timing belt. Normal use n Severe use. For the Optra ty only mention one mileage so I think that is the Severe mileage. I was doing my own check on what is the Normal mileage to change.

 

At least now I know its abt 80K km b4 I need to change.

sounds a bit mechanically challenging to the layman to remove cover. U DIY?

Yes U can DIY.

General rule that my mech told me is to change the rotor for every two pad change. $1900 for rear or front or all four? Almost half price can change all four rotor + pad + sensor.

I previously owned both C180 (supercharged elliptical lights) & E250 ( current turbocharged). Changed both rotor am disc at about 70000km. Had changed the pads frequently though. The rotor and disc in the C class are actually manufactured by Brembo. When I drove a 1.6 Japanese car, I had only changed the pads even when it hit 110000km. I think with force induction cars, you will drive harder and brake

heavily. I drove my E250 until it had grinding noise from brakes, the pads & rotors were very worn down.

 

 

Why is that the rotor for Jap cars last longer than German cars?

German cars are over-engineered, Japanese cars are engineered for simplicity.

 

Japanese and Swiss mechanical watches - which is easier and more pocket-friendly to maintain?

Facepalm... incorrect explanation bro

 

German cars are rated for the Autobahn. They must be able to withstand braking from Vmax to a standstill 3 consecutive times hence the pads are more abrasive and the rotors have a higher min. thickness. Of course you can run 3-4 pads on one rotor, but in an event you need to brake hard from a high speed, e.g. emergency on NSHW, the worn down rotor with less mass might not be able take the heat. One rotor for my BMW costs less than $200... I won't bother saving on this kind of money (~2 tanks of fuel?) for safety.

W204, C200.

 

 

 

your brake pad can last 100k+ ??

Nay... I hope that I can do that too haha

Every 25k to 30k change front pad... Rear ones agar agar double that
