Where do you put brake fluid for a 1992 Acura Legend and what type do you use?

When you open the hood from the front, the brake fluid reservoir is to your extreme right mounted at the top of the firewall between the engine and driver. My 1992 Legend LS manual recommends DOT 3 or DOT 4 but NOT DOT5. Of course they want you to use Genuine Honda Fluid. Topping up the fluid to between the max and min mark is what is needed. If the fluid is below the min mark, your brake system definitely needs attention. If the pads are nearly worn out the fluid level will drop below minimum. Don't top up the fluid in that case get the pads replaced. No offense, but for you to ask this question indicates that you have minimal knowledge of the system and would be better to get proper help. Good luck
