Rear brake disc size?

[TubaMagna8]

Fitted new discs to the front on my 2013 prefaeclift yeti however i didn't order the rears as most websites quoted two sizes. Anyone a better way to make sure I order the right ones with out having to take the old ones off?

 

It's a 2013 yeti elegance 170bhp 4x4

 

Thanks

Find the build data sticker in the boot or service book and look for a PR-code that specifies which rear brake set-up you have. It will be 1KD, 1KS or 1KJ, corresponding to one of the three last diagrams here: wheels, brakes Yeti (YET) [EUROPA 2013 year] (7zap.com)

That's what the impact wrench is for lol

Even my local garage had fun undoing the carrier bolts, after I had given up on DIY.  That was with a 2WD setup with better access.

My local garage got the job after I failed, they had to acquire 2 x new 12 point pieces to loosen the carrier bolts  --  a lesson there somewhere, total cost, 1 hours work 50€ all in!

I'll echo the pain with the carrier bolts.

 

My failed on my first attempt on my 170 4x4, as I couldn't find a combination of 1/2" drive extensions or flexible joints that would fit through the suspension arms & driveshaft.

(Also note I found then I I'd bought the wrong size rear discs, and the EBC Yellow pads - that I'd sprayed black for stealth - were also the wrong ones, so had to abort that too. I still have them sat in the garage, even though I don't have the car any more....)

Had to buy a different triple spline tool of a different length to even get on the bolt.

 

Managed it on second attempt, but had to jack the car up really high, so I could get a good pull on the driver bar to crack the bolts loose.

 

They're really tight, and really hard to get to.

So bit of an update, Got to the rears all the pads and discs where correct. Pulled something in my arm trying to get those bolts off, ended up using some old play Frame bar on the end of a long wrench to get the bolts shifted. Incredibly happy that I managed to do it all myself, with a little help from my dad as well. 

 

 

Old Discs and Pads

 

 

Said bolts, Was really pleased that the spline bit didn't slip at all after previous bad experience with them.

 

New vs old... (front ones)

 

 

New ones on, Been driving on the new brakes for a few weeks, really impressed by the performance of them. and they look the part too.

 

Thanks for the help in getting the correct disks and pads!

didi you really do that whole job using the cars widow maker jack? 

[Expatman]

NO, NO, NO can’t have done all that work with the car jack, surely used axle stands or something - tell us you did!

so I used the jack to raise the car, but then used the wheel under the rear subframe to support it but also had a solid wooden box with some planks on top which took the weight of the car, as before I started any work I let the weight off of the jack. 
 

I need to invest in some axle stands at some point.
