'05 Legacy recurring brake shudder

[UnitedWeFall]

Hey guys,

I purchased my 2005 Legacy 3.0R from Winger last December. After a few months it started getting pretty bad brake shudder. Winger had a look and replaced the front discs as they couldn't be skimmed. This fixed the shudder.

A couple of months later the shudder slowly started coming back. When it got really bad, I took it back to Winger who replaced the front pads and skimmed the discs. The shudder was fixed again.

It's a couple of months later now and the shudder is slowly coming back again.. I don't thrash it at all, most of my driving is on the highway. Is this a common problem with this model? Can anyone think of what could be causing it? Surely brand new genuine pads/discs last longer than a couple of months =/

Any info appreciated.

Cheers

slighty seized caliper wearing down the rotor and warping it over time? never had that kind of issue with my 3.0r yet but then i have changed alot of mine to non factory items

did you bed them in properly. i would go up a hill and use the brakes a lot on way down and see if it fixes it as they can get pad material on disk not uniformally

Yeah one of the mechanics took it for a spin after the installation so I assume he did it properly

try the heavy braking, like get them hot then let cool off while cruising

kk, will give it a try. Thanks

only 2 reasons I know of that cause recurring brake shudder

1/ Wheel nuts are over tightened/tightened in wrong sequence

2/ operator issue, riding brakes, sitting with foot on brakes for extended periods

In my travels #2 is the main culprit I see

what about a loose hub nut or worn wheel bearing?

[funkytown]

something has to be misaligned in the hub. I bet its only on one side right? So either you have a caliper that is partially seized or sticky, and you have a bent hub or loose wheel bearing or something.

Lets assume you've had a wheel alignment in the past while, and it comes back fine should rule out any funny play in the hub. Also you should have had a warrant check since December, a WOF should pick up a bothered hub.

Do a caliper seal overhaul and see how that goes imo.

You would think that as he has had pads and disks changed at WINGERS that they would of seen if the caliper slides/seals were buggered also it could be a loose hub nut/wheel bearing but once again it has just been to WINGERS so I gather they would have checked/seen that as well

winger = not that flash.. tbh.

Thanks for all the advice.

I did one someone said and stomped hard on the brakes a few times. It seems to be a bit better.. Might just get it into a decent mechanic and get them to give the brakes a good look at. Don't really have the time or know-how to do it myself.

Its the nature of this model, fast accleration followed by hard braking, its how some people like to drive it, or its hard not to drive like this ;D
