996 GT3: Replacing front rotors

---

Instructions for changing the left front rotor: Proceed at your own risk. B) 1. Lift and safely support the vehicle. 2. Remove the left front wheel. 3. Turn the steering wheel to the right to facilitate exposure of the rotor and caliper assembly. 4. Loosen the brake pad retaining bolt (13 mm hex) and depress the retaining flat spring. The 13 mm hex head is on the inside edge of the caliper (not visible in the pic below). Take note that the flat spring is VERY stiff. 5. Remo

Love this write up. Two questions. Would this apply to a regular 99 996 as well? And, for clarity sake would you draw arrows to steps 3, 4 and 5 in the pic itself? I am mechanically stupid so the greater the specificity the better. Thanks for an excellent write up.

How easily did your rotors come off?? Did they need some gentle persuasion?

When pushing the pistons back to make room for the new (much thicker) pads, did you have enough capacity in your brake fluid reservoir to prevent overflow - or did you bleed a little brake fluid off?

I take it you didn't bother checking run-out of either the hub or the new disc after you put it on.

Is there no loctite needed on the caliper bolts on re-assembly?

Excellent write up. I will keep this one in the archives.

Thanks!! :cheers:

I agree: Exellent article.

I want to add a few points:

The caliper bolts are 10mm Allen-wrench bolts. A regular hex wrench will not work.

And if you want to torque them when you're done, you'll need a 10mm Allen-socket to use with your torque wrench.

Lastly, I easily removed and then replaced the caliper without removing the brake pads, saving lots of time.

Plus, I rested the calipers on an upside-down bucket, rather than tying them to the suspension.

Just did this with my 997 S last week. I let the

caliper dangle on a jack stand. I like your string idea

better. I think I had to use a 13mm hex wrench

on my calipers. Good job with the pictures.

Is there a trick to depressing the flat retaining spring (in the calipers)? The ones on my boxster brakes were no where NEAR this stiff.
