Changing discs and pads tomorrow on bug sti is there anything not the norm I need to be aware of and are the rears easy with the handbrake shoes being inside them ?
Thanks

Just like any car really... There easy if all the tools are present
The fronts are ok... Are they four pots...?

Basic principles are here.

Be careful with Brembo's as the caliper bolts can strip the helicoils.

https://www.scoobynet.com/technical-...sc-4-pots.html

With rears, ensure the car is in gear, chock the front wheels and leave the hand brake off.

The discs can stick on, so loads of lube and a good rubber hammer to batter them off.

Or do this.

the front brembos have a tendency to snap the bolts then require a helicoil.
rears makes sure you wind the handbrake adjuster right off and they come off ok.
the adjuster is on the rear of the disc.

Basically what's already been said mate, but make sure you slacken the rear handbrake shoes right off. Don't force the rear discs off, they should just slide off if you have slackened them off enough. Otherwise you will end up with snapped springs and clips everywhere!

Any images of the bit of where to slacken the shoes ?

Thanks mate just got to try and work out how to use that link lol

Second this. Did my Brembos on my MY11 2 weeks ago, only 3 years old and 3 out of 4 threads stripped on the way out. I put helicoil inserts in all and bought new high tensile bolts from local fastener firm 1/10 price of subaru. Better than new!

Has anyone else had this problem I'm abit worried about this now, ?

Its a common problem to snap the bolts and know way of knowing till you try them.

terzoscooby

I knew the risk was high so bought everything before starting job. Took me 6 hours but saved a small fortune by doing it myself.
With yours being much older there is a chance they have already been done.
Threads are M12 x 1.5p. I used 16.7mm long helicoils M12 x 1.5p. Which is a fine thread metric so not your standard M12. Bolts are M12 x 1.5p x 35mm high tensile set screws. Would only recommend doing it yourself if you have a pillar drill to drill and tap the calipers square.

Thanks for all the info chaps, there all done no dramas thank god

Glad for you mate. Chances are they have been helicoiled already. Take it easy on the bedding in process.

Yes only one of mine stripped thread and needed helicoiling.helicoiling is not really recommended for brakes but these bremos suffer 'galvanic corrosion' due to the calipers being aluminium & bolts being steel,so if you simply re-tap a new hole it will only happen again,unless you could use an aluminium bolt which I dont like the sound of either,so helicoiling seems the only option and I haven't heard of anyone having dangerous issues,yet!

yup its a very common problem, once helicoiled it wont happen again though but that wont help the first time.

terzoscooby

Using high tensile stainless steel bolts would stop the corrosion but they are difficult to get in the thread size.

scoobyJim2

Well perhaps people could re-tap new hole to match the thread of a high tensile stainless bolt if they don't corrode and react with the aluminium. Would be better than helicoiling in my view.

terzoscooby

Helicoil inserts provide a stronger assembly than direct into alloy threads. This is because the inherent flexibility of the insert provide a balanced distribution of the loads. Thread wear is also reduced. Being stainless it also means there is no corrosion issues.
To be honest the manufacturer should helicoil but I assume they don't bother to cut cost.

Painted the inners so they don't go rusty

scoobyJim2

They charge enough for brakes new,surely they should helicoil for free at little expense to them if it was approved. My mechanic said he was taught its not advised to helicoil brakes.

CBetts

Think that's the general rule of thumb, however lots of people have had it done. I haven't heard of any issues .......

scoobyJim2

One of my brembos has been done,I haven't heard of anyone having problems with it either but as you say rule of thumb I wouldn't think was advisable

terzoscooby

Check any engineers hand book. Helicoils are stronger than tapping direct into alloy. Not many mechanics have an engineering degree!
