My Chilton Volvo repair manual ( 1970 to 1983 ) shows ( DOT 4 brake fluid )
DOT ( 4 ) brake fluid , according to my Chilton Volvo ( 1970 - 83 ) repair book
Your brake master cylinder may be leaking. Have it checked by a technician.
No.
DoT 4
no you have a brake fluid leak somewere
Top off the brake fluid resorvoir.
This is an easy one... Is the fluid green? if it is, it's coolant.. if not, its brake fluid.
A brake fluid leak in the system would do that. Check the brake fluid reservoir. If it is empty you are in need of brake work asap!
ouch,are brakes adjusted correctly/ sit in vehical and pump pedal to get a full pedal,then hold pedal to see if it bleeds off and goes to floor,if it stays, replace shoes and pads if it goes to floor, there is a fluid leak somewhere is there brake fluid in the resevoir/ are there any brake fluid leaks ,check backside of wheels there is a brake fluid pump, on the chassis rail about level with the front of the front door on the left side.if this pump is bad your pedal will go to the floor
Brake circuit failure. Normally this means the brake fluid level is too low.
The brake pedal will sink to the floor when applied and the brake fluid reservoir remains full.
