Hi. 

 

I'm in the middle of changing rear disc brakes and pads on my mk3 octavia 4x4 150bhp. I was dumb enough to belive in a youtube tip of where they say its not needed to remove the two (per side) xzn-bolts. The caliper is possible to slide off without removing. Sounds tempting, and might work on some models, but it for sure didn't work on my 150bhp 4x4 model. So I had to try to remove these two bolts (image number 3). They were really stuck so my zxn 14mm tool that I had with 3/8" was not enough. Didn't get enough power. Bought a zxn 14mm that had 1/2" connectivity. Tried a could of options before I was able to use a bended slidable weelnut bolt 1/2" arm and the zxn M14 with my feets to get enough force. My 450NM Impact wrench wasnt powerful enough, or I didn't let it work long enough, though worked late and didn't want to make too much sounds. 

 

Though since 've released two so far I guess I should be able to get all four soon.

 

So the question: Do I need to change or should I change bolts?

 

I've check the manual and it says replace 3, so I guess I'm answering my own question. But what happens if I try to reuse the old once? They look fine. 

 

 

 

 

You are suppose to get new bolts as they are stretch bolts but a lot folk and just reuse them.

When I did mine new bolts were supplied with the pads.

In my meike kit the bolts number 18 in the photo did follow the kit, but the bolts nr 3 did not follow the kit. Guess I'll buy them at the dealer. From experience these kind of bolts usually ain't that expensive.

Ah, yes. I misread the lines. Reused the mounting bolts.

I replaced mine, however alot of people just reuse the current ones

Think I ended up paying about £16 from VW for a set of 4

Oh wow. In Norway the prices from the dealer was 482nok = 34,5 pounds..! Though thats 3+13 a total av 6 bolts. 

 

Seems UK is much cheaper on original parts.

Best practice is to renew as you are aware, they are torqued up a lot TTY bolts. I have re used before though.
