Dot 4+

Just bougth 2001 volvo s40. i need to top up the brake fluid just a bit. Owners manual mentioned that it needed dot 4+. i could not find in any of discount parts.

volvo dealers quoted $20 for a quart.

can i use dot4 instead of dot4+ ?

( i have posted the question in volvoforum but it seems nobody knows either. )


You might just use the dot4, or pay more. The price is small. You might want to check the brakes, because if the level is down, it might be because the pads are getting worn down. Maybe check them anyway.
