You can either
Clean the old ones (waste of time imo but you could if you wanted to)
Buy new standard ones
Buy stainless steel ones

I went with the stainless ones from Godpseed Brakes (about £100) just to make sure that sticky calipers wouldn't happen again or you could actually get Godspeed to refurb the calipers for you.

Hi
It will be the pistons that have rusted that will be causing your issues , just changing the seals won't fix it , we are offering our pistons and seals for £109.99 a set , and these will never rust and should outsee the rest of the car !

Well I went with the stainless pistons from Godspeed and they do make a very good improvement (along with fitting his discs and pads )

After inspection, My piston was sticking on the rear caliper (despite having new pads & having them replaced 3 months previous) I lost my job & funds were low. So I delved into the unknown, bit the bullet & did it myself.

I had to cut off the rubber hood over the piston to get to the piston (It had split anyway) I gently tapped out the piston from back of caliper, spent some time cleaning the piston & bore with brake cleaner, de-greaser & wire wool & very fine wet& dry paper. I took out the seals & inspected them which were ok, so I cleaned them, the seal recess, bought some rubber grease & greased everything back up & re-placed it & put in brand new pads & bled the brakes.

And they worked a treat & it felt good. Really good. I had come to realise that despite inspections & m.o.t's etc, the brake had been binding for a long time & I have now gained approx. 5 MPG!

before re-fitting tho, I was concerned about the rubber piston cover so rang my local Subaru specialist who rally them, who said the pistons work better without the cover, as they cut them off & shunt be a prob on the road but in winter you need to inspect/clean them every now & again.

I don't think any garage would have stripped & cleaned them properly to the extent I did & I wouldn't have that much satisfaction either.

Morale of the story: You gain a lot by not replacing that doesn't need it, don't waste money you don't have to & gain confidence by doing it all yourself : )

Your right mate only thing worrys me is bleeding the brakes

Get an Eezibleed kit. Fairly cheap and easy to use

Keithys

Yeh ive seen them will do cheers

You mention about mot inspection. Trouble is imprezas can't go on the brake rollers as they're 4wd and the testers mostly don't bother with a tapley test on the road so they never get checked properly unless you do it yourself.

That's a good point Jason. You also need 2 jacks if you want to paint your calipers as I found out!
Keithy's, I bought a 'One man brake bleeder' from my local car spares which was brill. Ask a mate or your dad to pump the brakes whilst you bleed them. Piece of ****, just takes patience & a few pumps to get all the air out.

Keithys

Brill will do cheers mate

Let me know how you get on mate.
Its fresh in my head, so if want any more tips let me know.
P.S: If you can't get a brake bleeding kit, buy some clear tube from a D.I.Y shop (Same diameter as ur brake nipple housing or get some motorbike fuel/ battery pipe. You also need a clear plastic container or a glass jar or even an empty cleaned out food tin & find a lid to fit it & tape it round so its well sealed. Cut a hole in the lid (small enough to fit the pipe through) pour some brake fluid in the bottom of the container/pot & submerge the other end of the pipe in it & the top end on the nipple. By submerging the pipe in the fluid, & sealing the top of your container, you wont suck as much air back up through the pipe when pumping/ bleeding the brakes & you will get the air out quicker. : )

Keithys

Will do mate i will be doing it nxt wkend as were away this wkend drove home in it tonight and its really sticking bad when i got home the paint on the caliper was bubbling so i will be using the smart car till its done lol
