slight break judder at high speeds

[BJM555]

hi my 05 wrx has a slight break judder at anything over 70 any idea on how to fix it thanks

[Jay762]

is that judder when you hit the brakes at over 70 or just a judder from the brakes when driving over 70?

[Scooby Pete]

Warped discs seems the most likely cause especially if it's when brakes applied.

Daft question How do you feel it ? Though the stering wheel or more through the body

I've got juddery brakes too, and put new discs and pads all round and it s still juddery. Could it be wheel balancing?

[BJM555]

thanks yeah its when the breaking at or over 70 can feel it through the steering wheel

Or alignment or slightly buckled wheel,

I rotated mine last month and had horrendous handling, but my rear alignment was so far out due to the fronts being wrong I had a an unworn shoulder of rubber that was the cause due to ub even ware

Likely to be the front then, like pete says cooked discs. How new are they ?

If you fitted them yourself did you clean the hub properly? If there a bit of crud on the hub the discs won't seat properly and will be crooked Possibly causing the wobble.

Also have you checked all the bushes and rubbers on the front track rod arms and wish bones? May even be a bearing issue altough both these should be pretty evident weather breaking or not.

Wheel balance issues generally only show up at a small range of speed. Say between 50-60mph they either smooth out or get worse depending on how bad out of balance they are. The same as buckled wheels both these issue manifest weather breaking or not.

they are bout due for replacing is there any disks you would suggest 

[Scooby Pete]

Regards the warped discs.

It's hard to see by eye they only have to be slightly warped to cause judder So an easy way to check is to jack the car up off all four wheels if poss.

Take the wheel off and hold something like a pencil or the end of a pen against the disc, get a mate to spin the other front wheel and see if the disc moves away or pushes the implement. If it does then I'm afraid you've got a warped disc.

Ive used EBC turbo grooved and Turrox, Turrox warped on me EBC have not missed a beat imho.

2nd ebc discs and either green or redstuff pads maybe not geeen for the scoob.

I'm looking at black diamond for the fronts next month though.

[BJM555]
