Changing discs and pads, LCR Brembos

[8bit]

Need to change my discs and pads soon and found a guide in the Info Base section of the site (does anyone still use that?). Anyway, here's the guide - http://www.seatcupra.net/index.php?option=com_content&task=view&id=36&Itemid=6&limit=1&limitstart=0

Just a couple of questions:

1 - Do I need any particular type of punch to get the retaining pins for the pads out?
2 - The guide says the author doesn't know if there's a specific torque value for the bolts that hold the calipers on to the hubs - anyone know for sure?
3 - Is the copper grease a good idea? Seem to remember someone once said it isn't.

Cheers

4mm Punch from memory.
There will be a specific torque, however, what that is I dont know... I just do them up tight. They are VERY tight in my experience.
I dont Use copper grease, as the Pads I use on the road cars have an anti-squeel backing to them.

Thanks Dan. I'll be using Ferodo DS2500 pads - do you know if they have this anti-squeal backing?

I'll have a check tonight for the torque setting for the brackets, not got the laptop with me at the mo

If they're anything like the caliper carrier bolts on the LC, they'll be around the 110-120Nm mark.

Cheers Craig Fingers crossed it's no more than 110 otherwise I'll need to add a new torque wrench to the shopping list.

If I wanted to change the fluid as well, would a Gunson Eezibleed be a good idea?

When are you doing the brakes? If it's 120Nm then you can get a loan of my big een

 

[Dan1720v]

Its not that high as they're going into ally brackets iirc.

Cheers mate, could probably do with getting a bigger one anyway for doing wheel nuts so will price em up first

From the guide its not the hex-head bolts holding the caliper to the adaptor bracket, its the bolts holding the bracket to the hub.

No probs fella, just give us a shout if you need it

Hmm I thought the caliper just bolted straight on to the hub? I was looking at the picture below, you can see the two holes to the right of the actual wheel hub:

In any case, the guide only says there are the two bolts holding the caliper to whatever that is, if there is a torque value for those then that would be handy to know if anyone's got a copy of Elsawin/ETKA?

There you can see the two hex head bolts holding the caliper on to its bracket

The two holes in the pic you posted are for the caliper bracket to mount to, then the caliper bolts onto that.

The mighty Elsawin says...

"124Nm, splined bolt" - item 18 in the picture below. You might want to check if its a splined bolt or normal hex head

The caliper carrier (13) bolts onto the hub carrier (19) using two bolts (18) tightened to 124Nm.

The brembo caliper (4) is then attached to the carrier by two allen headed bolts (9) tightened to 115Nm. These allen bolts should be replaced when removed.


This differs from a normal caliper as the caliper bolts run radially to the disc as opposed to perpendicular to the disc face.

Simples!

Perfect, cheers - off to Screwfix for me then
