why are my breaks doing this?

Featured Replies

Hey guy, I have a 2003 Impreza running 315bhp breaks, 

standard calipers with black diamond drilled and grooved disks and pads. 

 

I had an issue before where breaking would cause my steering wheel to wobble at any speed. 

I had them skimmed as they were almost new and this fixed the problem

 

now its kind of coming back, it doesn't happen at slow speed this time and seems worse when the car is warm for some reason. at 50 - 60 it wobbles my steering wheel and at high speed (....such as 70 on the motorway ;) ) it shakes the car quite bad, enough to make loud noises. 

 

if i break really hard it doesn't shake but soft breaking does. 

 

I haven't done any hard breaking to warp them. what could it be as it's driving me mad !! 

don't want to spend loads on a problem that shouldn't be there in the first place 


Hi mate, 

 

Had similar issues with my'n, turned out to be sticking caliper warping the discs...

what was the cost to fix? if you don't mind me asking 

I had cusco scooby wagon do me a set of full refurbished calipers. Can't remember full price. Something like £225 and you get £45 back on the return of my old callipers. Something like that anyway lol. I can get exact price if you want mate.

Same as above mate, not too bad!

If it's around that that's fine. That may be cheaper option will ask my local subaru garage

OK I'll ask him now mate. For full price think you'll be looking at that for each. He also uses better pistons and you can choose what colour you want.

Cheers mate. If you have his contact details for me too please? :)

they are £160 for the 4pot front pr exchange + 48hr postage + surcharge of £50 that's returned on receipt of your old units to your paypal account.

That's what he's just replied with mate.

That 160 each side. I.e. 320 for both?

No mate all in about 225. With postage as you will have to pay to get them delivered. Once you removed old ones post them back to him and he'll give you back 50 quid. Once he gets the old calipers back. :)

Ahh that's not bad then :) thanks man. Will let you know just make sure my garage can't beat it

Sent from my D6603 using Tapatalk


OK no worries. It was the option I went with. And they still like new a year on :)

  • Author

And what's this about different pistons?

Sent from my D6603 using Tapatalk

Spot on not as prone to sticking as they're coated in ptfe type stuff. Well RCM said they couldn't believe how good they are :)

  • Author

May have to do that then!

Sent from my D6603 using Tapatalk

Paint doesn't chip off or anything every part is stripped rebuild and new parts added. I recommended them as a customer. Even though he's a mate too. Not sure Subaru stock calipers either but more than welcome to see for yourself. :)

I rebuilt mine using standard parts earlier this year and seizing again

Going to upgrade instead

He sand blasts them the lot. Could say they're new really time he's done with them. :)

My motto is if it brakes upgrades !!

No pun intending

  • Author

What cost would it be to upgrade though?

Sent from my D6603 using Tapatalk

Yours is a wrx isnt it chris?

 

TBH i;d just say sod it and chuck a D2 brake upgrade at it or AP for the big daddy. Stay away from Ksport though the dust seals on em are crap.
