Are they windback calipers at all?

One thing ive noticed with scooby is is that the handbrake works incredibly well, is the cabling quite thick, just curious.

Actually adjusting the handbrake, is it a case of removing the centre console and adjusting a bolt or is there more involved?

Cheers.

the pistons simply push back, but the h/brake is seperate
built inside the 'drum' of the rear disc, adjustment is thro' the rear of the backing plate for the hub, and also at the lever end of the cable......

Sounds interesting, so the backing plate for the hub do you mean by what looks like the dust cover?

And the drum of the disc being the centre part?

When i mean adjusting, i really meant the handbrake itself as mine is creeping up, id assume it's self adjusting so wouldn't need much touching anyway?

But im all for learning the car, i know pugs inside/out but the impreza is a different animal altogether.

Thanks for the advice.

Ah, by caliper drum do you mean the caliper pot itself?

A diagram would be a great help, hope im not being cheeky in asking you all of this lol.

evalscooby

not the caliper hux you were right the first time. hand brake is just like a drum brake, shoes, clips and springs, in the centre "hub" of the disc.

the h/brake is not self adjusting, like the old drum brake systems..............

Handbrake is seperate on a Scoob, it's drum brakes inside the centre of the disc.

Have a look here: https://www.scoobynet.com/wheels-tyr...djustment.html

Alcazar............just off out to do mine, since I've just upgraded to STi Brembos and 316mm discs on a classic.

Aah i see so the whole handbrake assembly is inside the drum, and to get to the adjuster you remove the cover and fiddle away with a screwdriver until desired.

Ideal, bit of an odd arrangement i must say but it seems to work very well, will find out when i have to adjust the thing for the new pads.

Are you putting on new PADS for the disc brakes, or SHOES for the handbrake?

If it's the former, you don't touch the handbrake unless you're fitting new discs.

If it's the latter, have a look at my thread on fitting rear Brembos. Lots of it is valid.

Oh so there's brake shoes inside the brake disc, how different.

Are they much hassle to change? can't see them being changed very often as it's not a part of everyday braking.

I will be fitting pads for the discs so that will naturally be straightforward.

The pads for the handbrake however i can envision being a nightmare.

So if this is the case the disc must also act as the braking drum for the handbrake so changing the pads must be similar to a drum system only that you have a disc to take off instead?

How ingenious.

Edit: aah ideal, just looked at your guide, my dad has a mitsi colt and the handbrake setup drum wise is near damned identical, should be a fair straightforward affair then.

The shoes arnt really that hard to swap round, quite similar to a normal rear drum setup

You might have trouble getting the rear discs off, make sure the hand break is wound fully down, and a big rubber hammer may be needed to free the disc up.
When you refit it, put some copper slip round the edge that slides onto the hub.

Takes around 3/4 of an hour per side.

Cheers, one thing though your guide about fitting the 2pot brembos, what years fit a classic?

Never really looked like that but it would be nice to have the extra braking force.

Staight swap id assume?

Up to 2005, IIRC


Absolutely not. You need a bracket, eg: the one made and sold by Welcome To Godspeed Motorsport, the discs and calipers off the STi, and a pair of handbrake shoes with much thicker friction materiel, since the STi discs, as well as being 316mm diameter, have a larger diameter handbrake drum, so your old shoes are no use.

Have a look at my thread on fitting rear Brembos, you'll see the bracket and the thicker shoes in a couple of the photos.
