Cracked Rear Disc Help/Advice...

[P17 TOO]

Was washing the car yesterday and spotted what's shown in the picture below on the drivers side!! Not sure how long it's been like this but f**ked me right off as I only had new discs fitted at the start of November last year and they're not cheap ones either but genuine Renault bought from Renault Wolverhampton! Have only done about 3k miles on them so for this to happen My questions are then the following please;

1) What would have caused it??
2) How safe is it to drive with exactly as I went out today and done a few emergency stops and braking seemed fine??
3) Should I be in a hurry to get it sorted??

Thanks

lol at doing emergency stops to test it!

I wouldn't drive it myself.

 

[MikeB]

I would defo get them changed asap. There been a few threads about cracked rear dics.

 

[Bluebeard]

I wouldn't be driving it thats for sure!!!

Do genuine Renault parts not carry a 12m guarantee??

 

[Laura]

prottom common for oem disks, gets them changed asap

Do genuine Renault parts not carry a 12m guarantee??

Should do I guess but I'm not sure how I'd go about sorting it out as I bought them through eBay from them?? Guess I can email them to see what they say...

I'm right in thinking I'll have to have both rear discs replaced yes?? Also will the pads need doing as would this have f**ked them up too??

 

[_WILL_]

I would def change the pads as well, its good practice to do it when swapping discs anyway, but in your case I would def do it, plus they cost f**k all.

 

[Martin!]

I just swapped mine on Friday because of the exact same problem. I wouldn't drive it 'til it's sorted personally, if it snaps, you're in a whole world of bother!

 

[.GAZ.]

Get that changed asap lol

DO NOT DRIVE IT!!

If it cracks completely which it will, Your wheel will drop off

 

[DannoTheGreat]

f**k me, in all my time of working on cars iv never seen a disk with a crack like that!

 

[Bluebeard]

f**k me, in all my time of working on cars iv never seen a disk with a crack like that!

I had one last week, on a 172. Looked identical! Could see light through the disc!

 

[172Ben]

Its cracking alot further down than just the disc.

I would be driving that really.

 

[Kele.B]

i wudnt drive it cos its part of the hub! :S

 

[saltyhair81]

that'll be seized hardcore. My bias was out big time and it was getting PIPING hot and didn't manage to crack like that

 

[rich-6]

that'll be seized hardcore.

Looking at the disks which have done 3k this i very true They look fucked already

s**t me! A few of my mates work for Renault, an they were saying the rear disks are prone to crack but i didnt think they meant that much

 

[Gray]

Hero...

I've seen quite a few, get it changed ASAP... I wouldn't even be driving the car with that!

 

[Triki]

Worst "i have got sportlines thread ever"



However stop driving it, or you will die fo sho !!

 

[caister]

As others have said I would say for the amount of wear on that disk that the caliper is sticking/seized which has probably caused it to heat up and crack. Mine have been on for 10k and look brand new.

 

[clio_luke]

common. happened to mine a couple of years ago.
do not drive it, replace with genuine discs, smooth and grease sliders on calipers while replacing discs.

 

[Paddy_g46]

look at the pic you can see the crack has gone right done to the hub. Get this fixed asap!

 

[P17 TOO]

So in conclusion it's really f**ked and I shouldn't be driving it!! I'll need to drive it to get it to a garage though so I'll just have to take it easy I guess :S Think I'll pay the extra and get Renault to sort it out...hopefully!

So from looking at the pic then the most common cause is likely to be that the caliper is seized on right?? What causes this then?? Also if this was the case surely they'd be some like grinding noise or something?? Had the sportlines fitted about a month ago so it couldn't have been like this before that otherwise the garage would have noticed and said?!?

 

[P17 TOO]

Been quoted £304.67 to have this sorted by Renault....LOVE IT!!

 

[Laura]

just buy some disks n pads off one of the traders on here n fit them yourself .. done

 

[P17 TOO]

I'm not capable

 

[Laura]

pay an indedendant then.. wont be anywhere near as expensive as reno

 

[P17 TOO]

That's what I done last time and now this has happened so I'm abit put off that idea now...probably no fault of the garage who fitted them but something ain't right for this to happen after 3k!

 

[Gray]

The rear discs and pads take about 20mins per side to change.. with a tea break

 

[Ay Ay Ron]

I'd do it yourself. Really not that hard to do. I managed to do new disk and pads all round in a day and i'd never done them before. Plus there are plenty of guides online.

 

[DrR]

£304!!!

Parts are about £120ish, and it's such an easy job to do!

 

[Jimbo-Clio]

Can you not get uprated discs for the 182? would they not be stonger tham the reno ones?

 

[Paddy_g46]

DO NOT PAY RENAULT £300! you must be mental, tbh after seeing some of the work carried out by certain main dealers I would much rather trust my back street mechanic to do my work. Also if you have any problems I find you are less likely to get fobbed off!

 

[Craigus]

If you pay Renault £300 to do that you are the biggest clownshoe known to man!

 

[Laura]

hell id do it for less than half that..
need to do the TT ones before i go away on sat grr

 

[mat-nos]

as said parts are £120 tops then an hours labour plus vat at a local garage your under £200........

looking at the disks though, your sliders may be seized so maybe think abot doing a caliper rebuild and fresh fluid etc which will still be cheaper than renaults price!!!

 

[hilldawg172]

you might wanna check you caliper!! when that happened to me its because my caliper had failed and was sticking could smell it when driving and could physically feel the heat when walking past it to close the garage on a night.
