Clio 172 rear disc change



  182 clio
you tried eBay?
And Euro car parts were about 8 or 9 quid for pads. With there discount offer.
That's what I fitted to mines.
#pads I mean 😂

Purchased the rear brake discs fitted with bearing and ABS ring. they look the same. And pads.

Went to fit it today, and am guessing the caliper hasn't been removed since date of first registration 18 years ago

Just couldn't get the bottom bolt of the caliper holder off. 17mm and tried, and tried, and tapped with hammer, and ring spanner, and socket, standard spanner and WD40d and everything. Wont budge- almost seems welded in! Top one was difficult , but got that one out. Couldn't remove the pads either (Took the little bar thing out) although I think I could've with a bit more wellie, as one moved a couple millimetres

I haven't rounded off the bolt by any means, but a 17mm socket wont hold

ANY TIPS?

Any ideas, or is it take somewhere to get them to loosen them all off for a few quid?

Have put it all back together, and may not bother again if they seem to work OK. Although the discs are well past their sell by date, and pads down to 2-3 mm.

What you think?

Impact gun.
Or good socket and big bar 😁
I take it there is some wiggle in your socket if your worried?

Is it just the cradle your trying to remove?
Yes- trying to remove cradle to replace disc.
Didnt wanna take pads out, although they wobbled ok, in case I failed on removing cradle bolts, which I did

Socket seems ok, as it sorted the top one, but a bit of room although the lower bolt just beginning to round off, have filed, and left to soak in WD40

Impact gun sounds good, have tried big bar- that's what got the top off.

Yes, I tried sifting though the sizes to find the imperial below 17mm
Found 16mm but that didnt fit

Thinking of popping into kwik fit or something, get them to crack them all off, then wheels back on, home, then do the job

😂
it should go try loosening the bottom first.
whack a 11/16 socket on it an get your breaker bar on it.
Checked my toolbox there to see what socket it was 😂

Many ugga duggas

If I remember right the last rear brakes I did similar. One side took a 17mm and the other an 18mm due to rust.

Be prepared to fork out for 4 new tyres, tracking, disks n pads.

All part of the service
LOL. Yes, have been to kwikfit b4 for a "free" brake and exhaust check

They tried to tell me i needed loadsa stuff, including a full new exhaust system (Which the leak they couldnt find, was repaired when I replaced the cat converter with a sportscat). I still made sure I came outta there not spending a penny. You've just got to NOT listed to them

I went in for a free allignment check after fitting my new shocks just so I could get a hunter printout, it was literally about 1 minute away from perfect but apparently it would scrub my tyres away in no time if I didn't pay the 50 quid for them to adjust it lol

Gave up with trying to swap the discs over, couldn't get the lower bolt undone. Tried again after soaking with WD40 and thought I had cracked it off, but it just slipped. Either going to try a new socket (Hex) , or a professional, or have a go heating the bolt up. Not sure

So- ended up just replacing the pads which was a PITA in itself. Removing and replacing the little metal bar was difficult, and didnt realise the retaining clips didnt come as new in the box with the pads, so had to hunt around for the old ones- least I found them. Caliper was dead stiff.

However, the discs look pretty bad, almost like the surface is breaking away- although they are not used for much I reckon?

you could try removing whole caliper there are 2 bolts in the rear which allows you to remove whole caliper just a thought.😁

So- was looking at photo below, which is nearside rear, after replacing with new pads, and wondering whether the clips have been put in right?

Looks like both pad retenrion clips hit the brake disc surface? So gonna go back and have a closer look as the brakes squeal occasionally

As you can see from previous posts, i wanted to change both rear discs as the outer inch seems destroyed. Now i think these metal clips have been the destroyer!

Still havent loosened the seized nut ( which is the lower one in this photo but on the rear offside) and am waiting for a new 17mm hex socket, or will heat the nut up if that dont work, so i can finally change the knackered discs.

And this is what i mean about the state of the discs. This is the worse one, but as you can see on the outer rim, this is where i believe those clips have been scratching the surface?

Do those clips have to be there?

They look like fine to me. Are they touching when spinning disc?
you can remove full caliper by removing bolts at the back of caliper

They didnt seem like they were touching the discs when I spun the wheel after fitting the new pads, but looking at the photo I am gonna double check. All I could hear were the pads touching the disc just a little bit. The brakes do loudly squeal when full pressure put on.

OK, Will have a look at the bolts on the back of the caliper bracket. I assume the 2 bolts we can see in the first photo are to remove caliper only, and the bolts you are talking about could be holding the bracket, that holds the caliper? That make sense

Didnt see those 2 bolts at the back, but will hava look see. Hope they aint seized too!!!

If you look at the rusty bit about 6 mm in the photo, between the 2 clips, that's the disc!

They both look like they are touching it- might just be the way the photo looks

EDIT: Thinking about it, the clips will bee on the edges of the brake pad, so should be quite a few millimetres away from the edge of the disc, but will look.

The 2 bolts you see in photo are to split caliper I.e to remove only cradle.
the 2 I'm speaking about are to remove whole caliper as 1 unit.
Did you coat edges and back of pads with brake grease or copper slip.
doubt it will make much difference with those disc's to be fair.
I strongly recommend replacing those disc's.

Gotcha

I didnt actually, don't know why as I usually do. Even had the copper grease in tool box next to me

Your telling me . LOL. But then again the fronts do %80 of the work, and they have new (1144) pads, and discs are good
 
  182 clio
And I still reckon it could possibly be those clips that have scratched the, outer inch or so, discs to bits like that
I think it's your pads buffing away all the build up of rust etc.
doubt those would even get close to touching as far down as that.
It honestly looks fine to me.
Just to replace disc's. 👍

The problem is that you've let the pads get so b*****d low and the boot on the caliper piston is shagged so your piston is probably caked in s**t and sticking now too which will cause it to bind

If you don't have the clips in then your rear pads will fall out and you'll have an even bigger headache

Also, how are you struggling with them bolts? Get a breaker bar and stand on the c**t if you have to
I have a breaker bar, and used it, and would have been happy to stand on it, but it slipped. That's why Ive ordered a new hex socket, although the bolt head is suffering from slippage on it. The one I used wasn't bad, but hoping a brand spanking new one will help. The bolt is seized- so any amount of standing on it will only, possibly, shear the head which I don't want. Last resort is heat up with blow torch, if that don't work, cut head off, drill out and tap a new thread. Lot of hassle for an old lady car.

In relation to your comment on the pads, the pads had around 3-4mm on them so didnt need changing really. The discs were on there when I bought the car, and as the brakes worked well, I decided to leave them alone. The pistons worked fine, as I wound them back no problem, and the boots both seem to be doing their job, even though the one in the photo don't look great.

Finally- other than the occasional squeaking, the brakes all round seem to be working better than ever. So I will continue to think about the best way forward, rather than resort to crash/ bang / whallop ;):):LOL:

To me, that bar inserted at the bottom of the pads seems to fix the pads in place with great force. Cant see 2 piddly pieces of wire holding them in place.

But hey, what do I know :)

the bar is there to stop the pad rattling when moving along uneven ground etc.
which is most of UK 😂.

Bottom bar is to stop rattle, spring clips are there to retain the pads when pressing against the mating surface.

Why don't you remove the 18mm bolts holding the caliper to the rear beam instead?
Yes, think that's what William84 suggested- so will have a go at that at weekend

18mm eh- they will be big n chunky then

let me know how you get on.
remember an check if you have spacers for your bearings. Not sure why tho. I'm sure someone on here will explain why they are there and why sometimes you don't need them.
As on my old disc's I had no spacer everything was fine but changed them and needed spacers before I could fit new ones.

Will let you know how I get on, but a bit nervous getting other bolts off, when I haven't succeeded with these. Just get on with it I reckon, asap.

Yes, seen quite a few just used the old ones, which is my intention

Good thing about having a separate daily driver, is if you need anything when Clio is up in the air, just jump in the motor and go buy it

Thanks for your advice thus far (y):p:D
