When flushing the brake fluid are you also bleeding from the clutch slave cylinder? I read that they share the same fluid.

That's correct. Make sure you keep the reservoir full so not to introduce air.

They share the same fluid but are divided. You can drain one and not the other. There is a wall in the reservoir between the 2. Below a certain point they don't share fluid. So if you bleed the clutch and run the reservoir dry it doesn't affect the brakes at all and vice versa.

So if you bleed one, you are not bleeding the other. They don't influence each other at all. Same reservoir, same fluid, 2 separate chambers

Put a small light behind the reservoir and it’s a lot easier to monitor fluid levels (especially with new clean fluid) and not run the rear clutch chamber dry.

ok just want to make sure I understand you.

I am going to pressurize the reservoir with the motive brake bleeder. All I need to do is release the valve for the slave cylinder and it will bleed. Just like the brakes right? There is nothing I need to do special for the slave versus the brakes to flush it/them

while doing this I need to make sure the reservoir stays fairly full.

Also. Is it recommended to use synthetic fluid on our cars ?

I bled my clutch slave when bleeding the brakes, the procedure is the same when you're using the pedal to push the fluid out. The clutch slave bleed line is the same size as the brake bleed line. I assume it would work the same if using a Motive bleeder to pressurize the system. I used Pentosin Super DOT4 fluid, trackday people claim it's a good value and it was the best I could find in stock at local auto parts stores.

In case you have trouble with your Motive bleeder, I used this method and it worked well (no helper needed):

Yep. And obviously occasionally check the Motive fluid level and pressure. But if all you’re doing is the slave it shouldn’t take much.

FWIW I like to keep a little bucket of dish-soapy water and an old rag close by in case of a spill. I can be clumsy in my old age.

Where is the slave cylinder located and what’s the best way to access it from the ground (no lift)

and yes. Old age. I spill everything.

Drivers side of transmission near the starter. The metal transmission undertray will need to be dropped and you’ll need a Jack and 4 stands. Since the bleeder is right at the aft end of the cylinder you’d want the car at least level. So stands at all four corners.

Got this project done

thanks everyone.

Use DOT 4. And nowadays I think they're all synthetic.
