Special tools needed?

Featured Replies

I am looking to change over my front discs and pads on my mk1 Octy today and was just wondering if there was any special fitment tools I will need to do the job?

Is it all normal and in line with everything else on the car as in star drive bolts or will I need anything more unusual.

Also I take it there's nothing to really worry about when changing them over on one of these, just the usual retaining bolts/screws and caliper out the way jobbie.

Cheers for any advice :)

7mm hex socket to get the calipers off 

 

7mm not a common size you can get a socket or a spanner type after made by draper IIRC

Ta for that, thought would check before setting at it and finding didn't have everything needed.

Will make sure I've got one first then.

Cheers for that :D

Yep think I have that in fairness, got loads tucked away in the box so just got to dig through to find it :)

Thanks again for that.

While i didnt do them myself, due to the tools shortage.... and a lack of self trust...

I did observe mine being changed and theres nothing to it!

 

Next time round I'm willing to give it a go myself... though id say the ramp vs axle stands is a fair easing of effort..

I have the halfords professional tool box got it refuced from 200 to 100. its got near enough everything for the basics... I did my front brakes a couple of weeks ago discs and pads

The only problem you might have is getting the single csk pozi-drive screw undone (holds the disc in place).

I had to carefully drill it out as it was seized solid, retapped the hole and fitted a new screw with a coating of copper ease.

 

Csk screw part number :-  N 106 483 01...... M6 x 16 long  (same screw for front and rear discs)

The replacement ones I recently got from TPS are torx rather than posidrive, which I suspect will be easier to remove in the future.

That screw only helps keep the disk inline when refitting. Not the end of the world if you have to drill it and cant replace it.

Thanks guys, well went to tackle it and got as far as caliper carrier and the. Came to an abrupt halt. No matter what I used on the 18mms they were not budging at all. Big ratchet, big ratchet with big bar. Bigger ratchet with bigger bar, followed by me standing on it and then a huge bar and all my weight up and down on them and not even a chirp out of the bolts.

Have sprayed them up with an anti rust corrosion spray and leaving them overnight and will try once again tomorrow.

Couldn't believe that these bolts just wouldn't shift.

I didn't have to worry about the posi screw as neither disc had one in so that's one less seized screw to worry about lol.

It's a shame they need changing really as they can only be months old on there but are warped badly and look to be cheap make so at least when my new stuff goes on ill know its better gear on there :)

they can get kinda fused on and can be a pain to undo.

 

Either impact (if you can get access to this) or penetrating fluid with some heat (worse case) if poss to help persuaded them to undo.

 

Tbh i have always managed to do these by hand, albeit lying on the floor and using my feet against the wheel arch to lever against.

 

that and lots of swearing...it helps...well me anywayw

what size breaker you using?

the two bolts that hold the carrier on were the hardest I got a lump hammer and hit my spanner to get them to start turning

you guys need to start eating spinach before doing these jobs..

a quick whack with a hammer usually frees off the disc locating screw.

Blow torch for the Win :)

Going to my mates tomorrow now to get it up in the air and then will have another go after the penetrating fluid has had a chance to work.

I'm not saying I'm "Mr Muscle" lol but I'm not weedy as I was really giving it a go earlier but they didn't want to budge but I know tomorrow it'll be done :)

A caliper rewind tool is handy to get the piston back. Even though the front isn't threaded like the rears i've still needed it on the front before

just used a big g clap and a bit of wood on mine

Don't forget the syringe for removing excess brake fluid from the master cylinder when you press the pistons back. Not needed if you follow Haynes to the letter by bleeding off the excess through the bleed nipples to avoid pushing muck into the ABS valves.
