Dfyhhh
There is a brake line vent tube on most Volvo trucks which allows excessive pressure to be released. This prevents catastrophic failure to the system.
These cars had issues with the pedal pressure sensor located in the brake booster. Additionally the brake booster it self is also known for failure on this car.
Brake circuit failure. Normally this means the brake fluid level is too low.
It indicates there is a problem. Get it looked at immediatly. Brakes are nothing to play games with. Your life (and others) depends on them.

My Chilton Volvo repair manual ( 1970 to 1983 ) shows ( DOT 4 brake fluid )
Bulb warning failure relay, a big round and red relay, back the ashtray
The 1991 Volvo brake light relay switch is located beneath the drivers side dashboard. The brake light relay switch will be above the brake pedal.
how do you remove the rear brake rotor on a 2000 Volvo v70 awd
Yes . Over time brake fluid can leak out and cause a failure.
The best way to free a stuck brake on a Volvo is with a caliper spreader. You can find one at an autoparts store or dealer.
