Good brand for DOT4 brake fluid

[kevindd992002]

I use a hygrometer to test the fluid. There are a lot of cheap ones in Lazada/Shopee. I noticed 2-2.5 years is about the time it takes to get to 4+% water.

But as *Vodka mentioned above, would using a hygrometer at the reservoir an accurate test?

thickness po sa brake pad.. pag di na kita yung guhit sa gitna, replace..

so after 16yrs of changing brake fluid every 3yrs i finally got some corrosion pitting inside my rear wheel cylinder, which resulted in a slow-ish leak. that's good enough i guess every 2yrs is going to be even better

Probably not that accurate but it will give you an idea how much water is in there. Flush every 2 years is the sweet spot for me.

Glycol based brake fluids (all except DOT 5) are completely miscible with water. Even with the limited movement of fluid from the master to the slave cylinders they should mix freely and completely.

Is this applicable for other oils (CVTF, engine, gear) too?





So even though the brake pads are still thick I still need to change them if they squeal? I hear occasional faint squeals only when braking while the road is wet/raining. I thought a brake system cleaning is the solution to that.
Fusion R says the pads are still thick and do not need replacement yet.

nopo.
only break fluid is formulated to be hygroscopic (attracts water).
oils are not, and they should better not be!
heh heh.

if the talyer-that-makes-money-by-servicing-your-breaks says you don't need break pad replacement, i will tend to believe them.

I will need to replace the brake fluid for my 2018 Subaru XV. I'm looking for a DOT4 brake fluid and there are several brands in Lazada/Shopee. I'm a noob so I'm looking for suggestions. If I want the best, should I go with either ATE or Motul? They are a bit more expensive but if using them matters, then I'm all for it. If using these expensive brands do not matter, what are other alternatives?

Add Bosch on your list.

DOT3 or DOT4 Brake fluids have best before dates if the container is plastic. If the container is metal, like Wagner, Mercedes, or Motul, there are no best before dates.
