Title: brake discs
Post by: psl on 10 July 2009, 16:15:01
ok so I've just got back from the MOT, and it did better than I thought it might, however it still  failed, front discs.

Ive had a look through the maintenance guides but theres nothing about the brakes, so is there any thing I need to know and does any one have the part no. for discs and pads and rough price?

Yes, full set :y :y :y

All you then need are two sensors 090495144 x2 £14-88 ex vat with Trade Card for the two. ;) ;)

For some unknown and highly stupid reason, it seems you only get 2 replacement caliper bolts, when you should really get 4 ... several members have had this problem.

If I were to buy the kit again I would open it in the dealers and check/ask for all 4 bolts !!

Not a difficult job, allow a morning - to include coffee breaks .. :)

Got the bits and for the fist time they seemed to take the abs card so got every thing for the righ price. :)

Whilst there I opened the box and there were indeed only 2 bolts, pointed this out to them and after a bit of head scratching got me some more bolts, then he said TIS says you only need 2 and I said he was wrong so he asked the spanner monkey who was there and he said they only take out 1 bolt and swing the caliper out the way but this wasnt very good as it put strain on everythin, so that could be the answer as to why they only supply 2 bolts in the kit.

Just got to wait till tomorow so I can fit them

I've started changing the discs and all is going well old one off new one going on, my question refers to the line in the guide

"Refit caliper mounting bracket, doing the 18mm bolts to 95Nm then angle tighten 30 degrees..."

what is ment by "then angle tighten 30 degrees..."?

Use your torque wrench for the 95 Nm then turn the bolt by a further 30 degrees. Specific angle guages are available, but I'm sure you can guess 30 degs or even use a kiddies protractor & a bit of paper!  :y  :y

What it says really ... take up to 95 Nm on the torque wrench. Stop . then tighten a further 30 degrees. Now you can buy posh angle guages to fit on posh wrenches .. but it is quite easy to "guess" 30, 45, 60, 90 degrees.

Just move the wrench handle to a sensible position before placing on the nut and tighten the number of degrees. It is easy to "see" 90 degrees .. its a right angle... so 30 degrees is just 1/3 of that amount. If you want you can cut a bit of cardboard - cereal packet ?? - and use that as a guide.

Angle tightening "stretches" a bolt a known amount, so bolts that have been angle tightened should NOT be reused as they have been taken to the "elastic" point of the metal.

edit .. must either type less or type faster !!!

I did think that might be what was ment but couldnt understand why a higher torque value wasnt just specified.

Torque values are highly dpendant on the condition of the threads and the surface the nut is rotating against .. if lubricated you will get a lot more tension in the bolt than if they are dry and corroded.

The "turning force" of the handle will be the same.. but one will both strech the bolt and overcome friction, the other just causes "stretch". By using a releatively "light" torque setting then an angle tighten the "stretch" or "clamping force" of the nut & bolt is far more accurately set.

If a bolt is tightened to "just" within its elastic range it will hold far better. Bolts that have high forces (head bolts) or are in critical positions (brakes, steering, suspension) use angle tightening for this reason.
