Would you track these brakes one more day?

R3ctivision · 04-22-2018, 05:44 PM

Front rotors have 5 days on them (originals), front stock brake pads have two days on them, and rear stock brake pads have five days.

Front rotors started showing hairline fractures after my last day out, one of which (not shown in pic) is barely enough to catch a fingernail. I've heard people run solid rotors until the cracks get more than few cm long. What say the forum, do these brake pads and rotors have enough life for one more day out? Notice the cosmetic part of one of my front pads fell off from the heat at the track

I would feel comfortable running those.

Rotors look fine to me for use. Top pads pictured definitely would be replaced if it were my car. (And I’m OCD so I’d replace them all at the same time).

Rotors look fine. Rear pads look fine. Front pad can be run if you keep an eye on them.

Remove the wear tab (I hate those things) so you don't scratch the rotor is pads get too low. Put the meatier pads on the inside, and the more worn ones on the outside. Run them and watch for wear.

Check rotor thickness with a caliper. Small cracks that do not reach the edge should be fine and are normal from heat.

Yes i would given the wear divets are still there but id watch them. Also keep in mind they may wear unevenly L vs R side. The rotors have plenty of life left. I ran mine for 15 days just to give you an idea. They had plenty of cheat checks but none got wide nor long. As long as none get too wide or start running towards the outside of a rotor it is just a sign of work. Happy tracking!

Thanks all! I'll give them a shot. I definitely noticed more wear on the inside pads, as well as a distinct taper as well (I guess working as intended with how the caliper piston sizes are staggered).

Also, thanks baron95 about the wear tab, will definitely do that.

Why inside?

Front pads: I wouldn't want to run those. They are fairly thin for a front pad to be tracked. So, your braking will be very susceptible to heat. You will get accelerated wear on pads that thin. If the weather is cool out, the track has some good straights for cooling and/or doesn't have heavy braking on consecutive corners, it will be OK. I would run them, but bring back my driving a tenth and also be diligent with brake conservation.

Rear pads: They are OK. I'd run them. They have decent material left and there isn't a ton of braking done with the rear brakes.

Rotors: They look OK. Run them.

Rotors look great. Run the front pads but bring spares. Check them with flashlight after every run session.

FWIW, it's Sonoma which doesn't have a lot of hard braking.

Be careful. Be cognisant. Check often.
