Rear calipers - no access to torque bolts
 

Rave page 149 (06-27) says the caliper fixing torques are as follows:

Which is all very well, but there's no room to get a torque wrench on any of the fixings in the first place. :shrug: :shrug:

Also, what on earth are 'Carrier to hub bolts'? :shrug: They must be referring to the front calipers because my rear calipers only have 2 guide pins and 2 caliper to trailing arm bolts (as per nos 6 & 11 here) - there aren't any other fixings.

Actually, that's not quite true. I can get a torque wrench on the lower caliper to trailing arm bolt, so that's now set to 64Nm. There's not enough room for the upper bolt though, so I've had to use a 13mm ring spanner (which isn't very long) and tighten it as much as I can.

I still have no idea how to torque the guide pins to 28Nm so it'll have to be an allen key and guesswork. :eek:

Anyone know the answer to this?

From reading RAVE it seems that the caliper housing is the sliding part containing the pads.
The caliper carrier is the part bolted to the hub.

The torque wrench settings table actually says "Caliper to hub bolts", ceasing to refer to that distinction. Confusing isn't it. :D

I work on these caliper carrier to hub bolt quite a lot and i don't worry about torquing them up,,, I use a 13 mm pro-quality ring spanner and once done up to the bolt head , I use my weighted nylon hammer to apply a good handfull of wallop to the spanner, usually three taps to tighten. Never had any issues with any calipers or getting then off next shout either.

The confusing bit is that there are 3 lots of fixings mentioned in the table when in reality there are only 2 lots of fixings. Here's a pic using Rave's terminology:

No part of the caliper (housing or carrier) fixes on to the hub - the carrier fixes on to the trailing arm - therefore there is no such thing as a 'Caliper to hub bolt'.

Forget all the pictures. Just do the two bolts that affix the calliper to the rest of the car nice and tight and tidy,,,job done! You don’t need pics and numbers to show you how to use a spanner on two bolts. Use common sense!!! Oh yeah!! That’s not so common!! ��

:wot::wot::wot:
You seem to be making a mountain out of a molehill:shrug: It's a simple job, don't make problems where there aren't any;):cool:

I don’t get all this torquing every bolt. Only bolts I’ve ever torqued is head studs and sometimes the wheel studs. I’ve never seen any garage torque brake calliper bolts etc, just tighten with a spanner

Doesn't that description apply to the front brakes?

Simon

I don't doubt it and that's one reason why I don't let garages repair my cars. :getmecoat:

I recall reading many threads where members ask for advice about brake servicing and the point is always driven home that this part of the car is of the utmost importance. When a torque figure is specified for something which is critical in terms of safety, it should be adhered to whenever possible, but extending this principle to other parts enhances reliability and a feeling of confidence.
