I’m going to be changing the pads and discs soon on my Scout. Before I get started and find I don’t have the right socket.... I understand that for the Octavia 2 you need a Torx head to undo the calipers. Is that the same with the O3, or is it a normal socket or an Allen bolt? Thanks.

13mm socket on bolt & 17mm spanner (I think) to hold the guide pin....& I think its a 20mm socket on the calliper carrier bracket..

 

Bolts are 35NM & 200NM....

Nice one, thanks.

No problems..

 

just remember that the big bolts can be reused..just clean them up..the small ones are supposed to be thrown away & use the new ones which come with the pads.....the only reason is because of the blue threadlock...so I just re-use & put new blue threadlock on...

 

 

Also you must check that the slide pins move in & out ok...if they are stiff they need to be removed...just pull....& re-greased & only use the TRW grease called PFG-110....nothing else as this grease is specific to the rubber..on the gaiters & the rubber bush which is on the top pin only.....I have had problems using other stuff....

 

also grease (lightly) ALL the contact points between the pad backing plate & the caliper, bracket/piston etc...also the spring clips & ears in the grooves on the bracket etc. Rust gets to these & corrodes them into the bracket & you have the pads stuck..just been there & done that...

 

Use a high quality copper grease...or..best if you can splash out is to get Loctite LB8009 (also known as heavy duty)...this is high temp graphite/calcium gears which is +1300C, stainless steel safe, high chemic resistant, & wash out resistant...but only in 250g tub & £25ish...

Finally got round to changing the pads and the discs today.

 

As most had advised really quite simple. The only difficulty was the Calliper bracket, where the bolts were factory tight, and needed gentle persuasion with a rubber mallet. The calliper slides were free, but used a recommended silicone grease on them anyway.

The old discs were difficult to remove, and again a rubber mallet helped. The new pads went in fairly easily, with some copper grease.

The main pain in the bum was winding back the pistons. It seems that when the dealer carried out the 3 year brake fluid change last year, they almost brimmed it. So despite removing the cap and being careful with the winding, I was greeted with a sudden splash of dot 4. When I got to the second wheel I had to place a collar of kitchen paper round the rim to catch the overflow.

 

Still all done, free moving and tightened, so off for a test in a bit.

 

One final point... when the dealer gave it the end of warranty service in June last year, they gave me a warning that there was only about 1000 miles left on the pad. 20,000 miles or so later, when I take them off, I find about 30% left, so a total of 70% wear after 55,000 miles. It seems odd, and quite disappointing that a year ago I was told they were 80% worn.....

 

Anyway, all set for another 55,000 miles or so.

 

 

oh, one more thing, the 2015 Scout doesn’t seem to have the low paid wear electronic gubbins on the pads I removed, so just had to take the clip off the new ones.
