Anyone know where I can get a Haynes-type workshop manual for a classic Impreza Turbo (1998). Alternatively, anyone got any instructions on how to change the front disks please?

Apple

very basic instructions:

Front Disc Rotor
A: REMOVAL
1) Set the vehicle on the lift.
2) Loosen the wheel nuts.
3) Jack-up the vehicle, and remove the front wheel.
4) Remove the caliper body from housing, and sus- pend it from strut using a wire.
5) Remove the disc rotor.
NOTE: .
If the disc rotor seizes up within the hub, drive the
disc rotor out by installing an 8-mm bolt in holes B
on the rotor.
6) Clean mud and foreign particles from the caliper
body assembly and support.
B: INSTALLATION
1) Install the disc rotor.
2) Install the caliper body on housing.
Tightening torque:
3) Install the wheel.
80 N-m (8.2 kgf-m, 59 ft-lb)
C: INSPECTION
1) Install the disc rotor by tightening the five wheel
nuts.
2) Set a dial gauge on the disc rotor. Turn the disc
rotor to check runout.

NOTE:
Make sure the dial gauge is set 5 mm (0.20 in) in- ward of rotor outer perimeter.
If the runout of disc rotor exceeds the limit, check
for abnormal free play at hub bearing and runout in
the thrust direction. <Ref. to DS-22, INSPECTION,
Front Axle.>
If the hub bearing is okay, replace the disc rotor.
Disc rotor runout limit:
0.075 mm (0.0030 in)
3) Measure the disc rotor thickness.
If the thickness of disc rotor is below runout limit, re- place the disc rotor.
NOTE:
Make sure the micrometer is set 5 mm (0.20 in) in- ward of rotor outer perimeter.
24.0mm 22.0mm 277mm
Disc rotor 1 I (0.945 in) ~ (0.866 in) I (10.91 in)
thickness A 24.0mm 22.0mm 294mm
(0.945 in) (0.866 in) (1 1.57 in)


This is for an MY02 but you get the idea...

Apple,

many thanks - really kind of you. I will give it a go at the weekend.

Fitted new discs and pads to my Scoob last night, it took a couple of hours and was dead easy.
Now have brakes that stop!!!!!!

glad to hear that you don't have to use the Flintstones approach anymore!

I cant get the hub nut off, the disc just keeps rotating.
Plus the nuts which hold the calliper on are bloody tight helppppppp.

I have literally just finished changing the front disks on my 1998 WRX and it was pretty easy. You should not have to take off the hub nut at all, just the 2 bolts holding the caliper body on. Once these bolts are out, the caliper slides off the disk and the disk simply pulls of the studs.

The bolts were pretty tight but I used a torque wrench to get the necessary leverage. Good luck!
