Hi,

I have a 2012 Mazda 3 Sport GS-SKY. I am planning on bleeding the brake lines in my car soon when I replace the brakes. I was wondering if I need to bleed the clutch as well? I found the procedure to bleed the brakes in the link below, but it does not mention the clutch. On the manual car, the brake and the clutch fluid is from the same reservoir so that is why I'm wondering about this. Has anyone bled the brakes on their manual car and need to bleed the clutch as well?

From what i remember when they replaced my clutch
Brake fluid was replaced. Clutch works on the same fluid.
Bleed from bleed screw on clutch slave cylinder.
On Brake ..you can use a vacuum pump, bleeder kit or gravity.

It would probably cost me more if i did... I just let my trusted autoshop do it..
Time is money to me.

The brakes and clutch share the same reservoir, therefore same fluid.

The system never needs bleeding or top-up unless the system has been compromised (opened to air). Example; a caliper, a brake hose or line has been replaced, then it would need bleeding and top-up.

Replacing a clutch in almost all cases there would be no reason to touch the fluid or to even remove the reservoir cap.

Bleeding the system unnecessarily, 'IF' not done correctly, can actually introduce contaminants (air etc) into the system and make it worse.

Testing the brake fluid for contaminants, (basically % of water in the fluid) every few years should suffice, unless ofcourse the system has been compromised.
