Morning all

Service time on the '03 WRX STi

Replacing all the brake fluid;

Now, I've got a Gunson Ezibleed which I've used on previous cars, but the cap thats on it won't fit on the Impreza reservoir;
I've not come across a reservoir cap like the one on the impreza - all the ones I've bled previously have been threaded, unlike the impreza which isn't !

Whats the collective advice for one man bleeding ?

Also, anything special about the fluid ? I've got a spare new bottle of Castrol SRF which I intend using.

cheers

Never found a one-man solution that wasn't a pfaff. My neighbour has a kit that works via his air compressor, it's OK but I'd still always use the 2-man method where possible.

Make sure you bleed in the right order or you'll never get all the air out.

It's a twin circuit, diagonally split system. So if one circuit fails, you still have F/R balanced braking.

It should be bled, NSF, OSR, OSF, NSR. As long as you get all the air out, it doesn't matter too much. However, you may find that if you bleed in a different order, you'll not get all the air and then you are just repeating the process. So best to do it the correct way first time. Also, you ideally need to cycle the ABS pump circuit also. To do this, drive the car and cause the ABS to activate (loose gravel or such). Then rebleed.

I usually bleed once. Drive for a week or so, during which time I will have activated the ABS and then bleed again.

bled the brakes today , i don't think the order of doing them makes much of a difference , i was worried about one inner nipple on the front brembos that was stuck but got there in the end , used a bit of wd40 first , fluid seemed fine but if the brakes are not done in the service schedule the bleed nipples are even more prone to getting siezed which can be a massive headache

thanks all;
yep - I thought the same re bleed nipples - careful squirt of penetrating oil yesterday to get them ready for removal this weekend (hopefully...)

Fixing a few bits & bobs too;
suspension is making a few noises, so all drop links, ball joints & strut top mounts are being replaced, and all bushes checked on the way.

Was halfway through NSF yesterday when the car had to be quickly put back together no.1 daughter decided to give birth two weeks early !

I've got the factory service manual for the car which makes things so much easier :-)
