Bleed/Flush brake fluid???

[Silver-Arrowz]

What's the difference? Same thing or what?

Your not supposed to mix normal stuff with silicone based fluids so how do you go about changing it?

[blind_elk]

With a flush, you change ALL the fluid.

This is how I did it:

Basically, jack up the car, and open the bleed nipple. The fluid will just drain out (very slowly). When the master cylinder reservoir is empty, fill with the replacement fluid. Then open each nipple individually, and allow to drain until the new fluid starts coming out (obviously easier if new / old fluids are different colours). ie open LR, drain, close, open RR, drain, close, etc.

Once all calipers are running new fluid, do a normal bleed to clear any air from the system.

and a normal bleed is done how

i keep forgetting which is quite stupid seeing i've changed my brake pads the last 6 times its needed doing on various cars.

Start at the master cylinder, apply brake pressure, then crack brake line (I can't recall if they have bleed nipples or not), make sure no air comes out. Tighten joint before letting pedal come up.

Then, start at the furthest point from master (ie RL), get pressure, crack open bleed nipple, close bleed nipple, then let pedal up. Repeat a couple of times to ensure no air is coming out. Then RR, FL, FR bleed nipples. Make sure you don't empty the master reservoir

and when do u know its a good time to change it?

If you don't know the last time it was changed

Bleed before and after a track day or every 6 months.

Bleeding your brakes isn't a part of normal maintenance. If you have to do it every 6 months or after a track day then you've got a fault in your braking system.
