Changing rear discs

[Cos]

I'm in the process of fitting new discs and pads on the car, just having a little trouble trying to remove the carriers

I can't get my head round to see what type of tool is needed to remove the bolts. I'm certain it's a splined bolt with a torx head, but does anyone know the proper size? I don't want to round them more than I have already.

Thanks

PS: Car is a 2006 1.8T FR

I don't think it's splined, I thought it was just an allen key required. It has been quite some time since I changed my own rear discs though.

Did mine recently. Like above its an allan key. And can be a nightmare to remove.

Yeah don't think I meant splined, it's been a long day haha. Any idea what size allan?

 

[R1ch85]

Could be 6 or 8, I don't remember it being larger than that, or smaller.

 

[vroomtshh]

It's 8mm.

And be careful with those bolts, because they are metric fine threads and not easy to get replacements

 

[Cos]

Tried 6, too small, tried 8, too big, tried 7, slightly too small :S

I fear I may have chewed the head to bits trying different types of tool, and may just have to drill them out

I had to hammer an 8pm in because they had rusted. It's definitely 8mm though because I bought new ones

why do you need to remove the carriers? I just removed the caliper from the sliders and removed the screw from the disc and a couple of belts with a hammer and the disc came off

I was thinking that,been 4 years since i changed my rear discs and pads but i don't remember needing a allen key but it could just be my memory going

I've changed the discs on a couple of cars with this caliper and not had to remove the carrier. If the disc won't pass, try turning it snd trying again

3rd'd - I got my rear discs off the last time without removing the carrier.

Calipers are 13mm bolt 15mm nut to loosen and the carriers are 8mm hex head.

I had the same problem with mine i thought it was a torx bit originally because it felt like there was alot of play in there !

i had to use a bar about 60cm and wd40 to break them because they were on so bloody tight i though i was going the wrong way at a point.

This will do it

But i bought a 3/8 drive hex set as they're hand to have around
This one

I managed to get the old ones off without removing the carriers, but the new ones are a tad thicker, and I don't want to scratch them up.

I was using a torx bit at first Lew, but it seems to have chewed it up a tad. Might have to hammer the 8mm bit in

Thanks for your help all

I did the exact same i think i was using a T55 or maybe T50 as it seemed to "bite".

Gave up in fear of rounding the nut off (which it had started todo) I hammered in my 8mm allen (hex) just to make sure it was in as far as possible - I think youll be ok mate just replace it with a new bolt after. Other guys recommended using thread lock when replacing so I did that too.

I agree with you, having rusted away quite a lot of material, the old ones come off easily enough, but if buying the correct quality of new discs, then you will normally find that they will not slip in without removing the carriers - I'm sure lots of bodgers do hammer them in, but what's the point in that when using new parts.
