First of all, HAPPY NEW YEAR!!

A question before I get under the car to check.

I replaced front brakes for big reds. Did something wrong because now, when I turn the steering wheel all the way in one direction while backing up or going forward the brakes lock up.

I am going to check that I did not installed the brake lines incorrectly but outside of that, what else could it be?

Got video ?
Are the tires hitting the body at full lock ?
Are the big reds hitting something at full lock and bending / binding the discs ?
If you jack up the car and remove a wheel , does it still bind up at full lock ?

Wrong spacers for the calipers, so they rub somehow? That would be my best estimate... or improperly offset wheels.

Wachuko

Same wheels and tires as before. Tires are not touching the body at full lock.

I will put it on the lift and check.

Wachuko

These were taken directly from another 964 and installed on mine. Everything works fine until I go full lock...

Wachuko

I will take photos/video when on the lift. Thank you!!

perhaps the rubber brake line in the wheel wells are getting pinched at extreme turning of the wheel , as the line is pinching its actually causing the brake calliper to apply the brakes, makes sense?

Wachuko

That is what I am thinking... But how can I get that wrong!?? Those have only one way to be installed.

Wachuko

Well... looking up the parts number I see that Turbo models have a different brake hose. So all this time I have been having this issue because I forgot to compare the brake line part numbers and used the existing one.

In the different threads I read before doing the brake upgrade I never saw a reference to a different brake line... anyhow, going to order a set of lines today. I hope that resolves the issue.

It calls for 928.351.971.01

Wachuko

Any comments from those that have done the change to Big Reds? Did you change your brake line/hose to the 928 or 959 part???

I used the ones in the 993T brake kit which I distinctly remember were longer than the stock ones I removed.

Thank you Marc.

Frank 993 C4S
