A class brakes!

[bash_8]

Hello

I am new to this forum and wonder if anyone can help.
I have a A140 and i had my brakes changed at 19k miles (service B). The indicator on the dashboard is coming up for brake wear and it has only done 30K miles ( a few months after a service A) - about 5k of these miles are motorway miles. I cannot believe the brakes are already worn. I was told that it should last for 20k miles. Can the indicator be faulty. The light indicator only seems to come on when i press quite hard on the brake and i am on an incline, so far anyway. It has been a couple of days.
Please help

Your discs may be worn a little putting a ridge on them and this is rubbing on the wear indicator when you press the brake hard or it may need new pads or they may not have changed the sensor wires when they changed the pads

Thanks for your reply...&
Could the sensor wires be faulty? I didn't realise they need changing...

Can you give me a rough idea of long pads should last with average driving habits?

Thanks

There can be a few problems
1 Check brake fluid level.
2 Remove wheel and see how pads are for ware .
3 Check wires are connected to brake pads.
4 If all this is correct come back and let me know.

Thanks,

I will do that and get back to you.

LAndover,

I have just done what you wrote and everything seems ok. There is still a few mm on the pads before the groove starts- is this ok? I didn't check the rear wheels should I? The main thing i still don't understand is that the indicator only comes on when i press on the brakes. The first time i had them changed the indicator would be on all the time when i am driving- not just on pressing. Is this significant?

if the fronts were changed (for arguments sake) and now its the rears that are worn - then this is acceptable..

light works by a samll bit of wire IN the brake pad (which whilst driving is not actually touching the disc) making contact with 'ground' [i.e. disc] so will initially only come on with braking..

30k seems ok to me though..

Well i had all my brake pads looked at and it turns out one of the four is very worn ( it has a wire sticking out of it- is that the sensor?) and the other three seem ok. How can that be? I have had them all changed despite only 10k miles since last time. Could this one brake pad been duff? Or is it do the cars braking system? Is seems odd that only one pad is very worn? Any ideas.
Thanks in advance

Have a look at the disc (the side of the disc the worn pad came out of ) see if it?s scored if not it?s more likely to be a sticking calliper, either the slide or the piston itself. Hope this helps

 

[bash_8]

No the disks were fine. Would i need to do anything about the calliper thing?

 

[bash_8]

Oh yes..

Is there i can do to prevent uneven wear in the future?

I guess thats my key question.

Check the rear of the pads for identical batch markings. It could be that they never changed all of the pads last time round!
