Rear disc Brake pads only lasted 6,000Kms

[Turbo_Boss]

Hello Guys,

I have a 2002 Octavia L&K 1.8T, at 35,000Kms the Skoda Dealer intalled new disc REAR Brake pads.

A few days ago every time I brake I hear the rear brakes screaming like iiiiiiiiiiiihhhhh. I check thru thru the wheels and the lining on the pads looks thin.

Right know my car only have 41,000 Kms.

1) Do the rear disc brake pads have the little metal thing that touch the dics to let you know that you need new brake pads? And this is what is making the noise when I brake?

2)Could it be possible that when the Skoda Dealer intalled the new REAR disc brake pads at the 35,000Kms service they intalled or adjust them bad and the pads was always touching the disc and I was dragging them all the time and thats why they only lasted 6,000Kms???

Tomorrow I have to take the car to teh Skoda Dealer and I want to know this issue because if this was the problem I will demand that they put new pads free of charge:mad:

What you think guys,

Isaac

1) no no wear indicators on the rear.

2) Either you've got a sticking calliper on both rear brakes or IMHO more likely they didn't install new pads as they claim.

:iagree:

[cheezemonkhai]

For what it's worth, my rear brake pads got replaced at 50'000 miles.

[KenONeill]

No idea how long the pads lasted, but my rear discs (and pads with them) were replaced on about 76_000 miles, say 121_000km. Even if you half that it still says 60_000km or better is not unreasonable disc life, and pad life should be about half disc life with modern asbestos-free compounds.

With FWD cars the rear brakes don't do a lot really; the dynamic weight distribution in emergency conditions tends to go towards somethin like 90% front!

If they fitted new pads on worn discs, that would not help :(

If they fitted new pads on worn discs, that would not help :(

And the reverse is also true; more so if anything. :(

One good thing about the 5-spoke alloys; other than not replacing inside pads, bodged or fraudulent brake work shows up to a visual inspection!

Hey guys, thx all for your coments.

I just talk with teh mechanic at the Skoda Dealer. He says that brake pads are OK and that the problem is that I need to replace my rear discs:eek:

They do not look damage or worn. I can pass my finger on the superfice and the fill is OK

I toll him how come!!! The car only have 41,000Kms:mad:

I toll him to fix the disc on a special machine that rectifie them. Is a machine that have a knife that remove the superfice of the dics and leave them like new...............But he says that from factory, does rotor disc are very thin and they do not recomend that method on does disc.

He also say that the Skoda rear brake pads are very abrasive and thats why they eat the disc.

So what you think guys??? My only problem is that when I brake the rear brake some times make a noise/scream like iiiiiiiiiiiiiiiiiiiiiiiiiiihhhhhhhhhh

Utter tosh as my rear discs are in very good condition even after i've been through a set of pads.

I don't for a second believe them.

Ask them to measure the thickness of the rear discs and what the new thickness and the minimum thickness are. If they are the non vented type they should be 9mm thick when new and if they are the VRS vented type they should be 22mm thick. Both of these will typically have about 2-3mm wear in total.

Also if the discs were so worn they were going to destroy the pads then why didn't they spot this and advise you at the service rather than just doing the pads. - They should replace the pads FOC in this case.

If they are claiming the pads just look worn because the disc is so worn, you can see that 2-3mm of disc wear isn't going to make a new pad look worn out as they are about 12mm thick new from the pair I have.

Also look at the pads and see how much meat you can see on them. there should be a good amount between the maximum and the minimum.

[vRSLen]

As we do not know all the facts, bearing in mind this is not the UK, it may

be to easy to judge previous judgement?

[RobClubley]

I must drive like an old lady as I am on all my original discs and pads after 4.5 years and 75,000km

Or I never slow down

[Turbo_Boss]

If they are the non vented type they should be 9mm .Both of these will typically have about 2-3mm wear in total.

Hey cheezemonkhai, THANK YOU for your explication. My car is not a VRS is a regular L&K 1.8T so I am pretty sure I have the 9mm one.

So you say the tolerance is only 2-3mm? I do not measure them but I will my rear rotor disc dont have to much wear on them.

I decide to talk with the Mechanics Manager and he toll me that I dont need new disc rotor yet. My problem was that they was very dirty and they cleaned FOC.

I took my car today afternoon and for the moment I dont hear any noise/screaming iiiiiihhhhh when I am braking:thumbup:

But just in case, I check with them the price of new rear disc rotor and each one cost US$ 42.oo So I will keep using my car as regular and I hope I dont hear does brake again.

Thank you all for your coments,

Isaac

Many years ago, I tried to get my brake pads uprated for my Strada Abarth 130TC. I took it to my local ‘specialists’ and they ordered and later fitted the pads. I went round to pick the car up and was informed they had suffered an unforeseen setback. The pads were the wrong thickness and were too thick to fit the car. So…….and I am not making this up…….they had given the 4 pads to their trainee monkey and given him several sheets of Emery cloth! Yup you guessed it, they got him to rub the pads down to a size that would then fit the car. I wasn’t happy and the monkey who had spent 6 hours or so on just one pad wasn’t happy either (he had made no head way what so ever).

[KenONeill]

TurboBoss,

I can tell you, from experience, that a worn-out solid disc does not make the pads look worn!

The squealing noise you report points at one of 2 things:-

1) New pads installed without the use of brake grease on the back plate and/or a missing anti-squeal shim (if applicable).

2) Worn-out pad making metal to metal contact with the disc,

(1) can be intermittent, and even go away altogether, but (2) can't be fixed short of new pads, and probably new discs.

Also, in this context, the 2mm is not a tolerance figure. It's the difference (reduction) in thickness between a brand-new disc and a worn-out one.

Amanda,

@Amanda - Brilliant, what a bunch of "specialists"

@Turbo_Boss

As Ken says 2-3mm is not the tolerance, it is what the disc is considered worn out at. I'm not sure on the exact figure, but it wouldn't htink it can be any more than this as the 25mm vented front discs are worn out at 23mm thick.

The Skoda dealer put the new pads at 35,000kms but just only at 41,000kms the brakes beguin to make noise BUT it can be possible wath you say. The mechanic that intalled does pad is a completely stupid!

When he intall the new pads I dont know why but he also fitted a new brake hose on the rear and he leave that hose a little loose and I was loosing brake oil on the rear.

1) I really dont undertand how a car with only 35,000kms will need a new brake hose on the rear..............The only think thats come to my mind is that he damage that hose when intalling the new brake pads.

2) I know that mechanic is a stupid SOB because he was also the one that fix one of my window regulator and checking the door cover there was 2 missings screws................He also leave my beige carpets all dirty.

When I pick up my car and saw all this mess, I was so **** off that I was screaming how the hell you are returning me the car like this. I also went in to the main office and talk with the manager and toll him whats going on and he fix my issues.

A week later, I bring the car again I demand talk with the Mechanic Mananger and explain all the problems and I toll him very clear that I dont want that stupid mechanic to touch my car and that he need to keep and eye on that mechanic because he will damage more cars. I toll him to cut his hands in order that he dont touch a car again.

I pick up my car the second time and now the brakes dont do the noise so its look they fix the problemo. Let see what happend on the next days:rolleyes:

I am still going to talk with the Owner of the Skoda company here in my country. I know him I have speak with him some times in the pass and I will let him know whats going on in the mechanics area.

2) Worn-out pad making metal to metal contact with the disc,

Thank god this is not my case. The pads look OK with a lot of meat and disc look very good.

(1) can be intermittent, and even go away altogether, but (2) can't be fixed short of new pads, and probably new discs.

I will keep my ears alert to see if they make noise again but until today, no noise...............Let see what happend on the next days.

Also, in this context, the 2mm is not a tolerance figure. It's the difference (reduction) in thickness between a brand-new disc and a worn-out one.

Amanda,

Amanda, thank you for your time and help,

Isaac

[KenONeill]

Cheers for that; I didn't allow for the worker in question being that much of a chimp! If you drive a lot on unsurfaced tracks it could be possible to damage a brake hose by hooking it on a rock sticking up, but that is no excuse for not tightening up the unions on the replacement properly!!

[Lady Elanore]

on the next days.

Amanda, thank you for your time and help,

Isaac

I thank you for your thanks Issac. But I think Ken misunderstood my post. It was just a little brake pad anecdote.

Glad you seem sorted:thumbup:

[KenONeill]

I got that Amanda, hence the .

Ah I think, having had a rethunk, that Issac thought you were attributing the 2mm thing to me………….At least I think he thought that, I now I thought that:O:D
