When to change brake rotors?

[Timmz]

On my last 60k servicing, the mech recomend me to change the brake rotors by the next svc interval. says there is uneven wear and some grooves appearing that will compromise brake ability.

 

Any one has some concrete ways to verify that. My brakes work fine so far, the occasional 'e-brake' to avoid crazy drivers. so far so good.

 

How do I tell the mech is not trying to wrangle me of unnecessary changes? Seems common on conti cars, my jap car experiences do not have such requirements till like 120k

 

inputs appriciated.

 

ps: no more warranty, is a rather low mileage car :)

60K? urs OPC?? should be under warranty, go back to ur dealer to change....

 

its not a standard part that required to be change on certain millage. But got problem at 60K is really quite rare.

I think rule of thumb 2 sets of pad then rotor. Conti brakes tend to wear faster. At 60k, I think no more warranty as brakes are wear and tear items.

 

Some work shop "skim" the rotors if it is not already too thin. Normally done only once, if scoure again better change.

Change rotors at 60K quite suprising, esp when you say braking still ok.

Your pads are stock factory types or the performance, aftermarket ones with metallic compounds?

[Timmz]

all compoents are stock.

 

any info on how to make sure that it is in fact required to change? the thickness of the brake pads n the rotor? such information is not easily available to the man on the street

[Eyke]

there is a minimum thickness for pads and rotors, you can check with your dealer/manufacturer for the specs since it's stock.

 

to make it easier to see, you may consider changing to rotors that has indicators for when minimum thickness is reached, eg. some Brembo rotors:

using slots for Brembo Max:

yesh go get brembo max disc...

 

cheap and good, slotted looks good and better than the flat stock

... i bought 160 there each disc... from Lintrex , brembo agent at yishun

Hi bros.

im driving a G6 camry with 30k mileage..

recently when i for my 30k servicing at an outside workshop, the mechanic asked me whether i wanna do some servicing for my brakes and i asked him to go ahead..

i saw him took out the brake pads and sand them on a sandpaper.

 

1 week after driving, i realize that there are 2 different tones on both my front rotors.

 

 

this only happened after the servicing. those it mean that only half the brake pad is working on the rotor?

wat can be done to solve this?

thanks!

Frankly , the mech has taken yr money and wasted yr time, trying to remove hard /glazed spots with sandpapper which achive nothing at all. It's like trying to polish a rare diamond with sand dust. The end result is the some fine abrasive from the sandpaper get in between the rotor and pad thereby causing uneven heat distribution on the rotor.

my civic mileage is 120k liao..everything servicing, they didnt say anything about changing rotors leh..

[Silver_blade]

Agree with Yeobh. What you mech did was 'rubbish'.

 

I guess you can try to skim the rotor and get a new brake pad. Or...you can just get a new pad. The 'damage' on the rotor doesn't look too bad.

[Axeman24]

Friend don't mind me asking did you use after market brake pads? If yes, it mind be the cause of grooves on your rotor. I experience it before and regretted using after market brake pads. So if your are using after market pads my advice is pay a bit more and get the original ones.

[Fabby27]

nope still on the stock pads...

[Fabby27]

these lines only appeared after the brake 'servicing'.. which probably mean that it has caused more harm den good?

 

wat's a cheaper alternative to solving this? skim the rotors or to change the pads?

if i leave it alone.. will braking power be compromised or would there be further damage?

thanks

[Yeobh]

If the pads are reach the min thickness, than I suggest replacing them, if not do a clean up. I am sure of the pad material, but try using a fine cut woodwork file if not possible opt for fine cross cut metalwork file.

dun like the tone? so how... go back to him and ask him adjust key + or minus?
