Where is the brake fluid resovoir? - 1993 Volkswagen Cabriolet

Hey Wild Bill,here's a link to a video showing you how to add brake fluid to your truck. Add Brake Fluid 1990 2000 GMC C3500 2000 GMC C3500 Sierra SL 7 4L V8...

it sounds like the brake servo isn't working but you should still have some better brakes than you dascribe so i would also check the master cylinder , whick is connected directly to the servo , quick check ,engine running remove, brake fluid resovoir cap, pump brake pedal and get some to look into the fluid resovoir and tell you is there are air bubbles or not , if bubbles most likely a seal has blown if no bubble then most likely a mechanical part of the brake system ie master push rod at fault , either way i'd get a mechanic to check as you dont take chance's with brakes

You don't need a diagram. There should be a small resovoir close to the brake resovoir. Look for a black or white cap the says either use only DOT3 or DOT4 brake fluid. They usually only have 1 line running from it. Don't over fill it, if it is empty you will need to bleed the system. Aldo don't get brake fluid on your car's paint, it will ruin it.

sounds like the concentric clutch slave cylinder is faulty/leaking, is there any sign of fluid loss from the resovoir, it uses the brake resovoir for its fluid supply, the leaked fluid is probably in the flywheel houslng, big job to change. front subframe has to be removed, if its a 2.5 or 3.0ltr transfer box also.

this is mechanical problem. go to

God bless you

Check the fluid for the clutch. It has a small master cylinder next to the brake master cylinder. It should use brake fluid. If it is low, top it off. If it goes low again, you'll need to investigate where it's leaking from. You could have a leaking master or slave cylinder.

You may just need to fill the brake resorvoir with brake fluid, when you are NOT pressing the pedal the fluid in the resovoir is low and the light comes on.

When you DO press the brake pedal you are forcing brake fluid level to go higher and this tells the sensor in the resovoir that the resovoir is full.

the clutch fluid resovoir is the same as the brake fluid resovoir

The brake light is probably on because your brake fluid is low. But this is also an indication that you brake pads may also be worn and need replacement. The brake system is designed so when the pads are low the fluid will drop in the brake resovoir and turn on the brake light. So inspect your brake pads or have them inspected. A leak in the brake system could also cause the light to come on. But do not ignore the light and find out why it is on. If the brakes are good and the fluid is low you could add some brake fluid to the resovoir but I would not top it off and if the light comes on fairl quickly then the brake system may have a leak.

there is a sensor in the brake fluid resovoir. if the fluid gets low, the brake light comes on. i'd say its borderline low and when you go up a hill it goes below the sensor level. add a little brake fluid to the resovoir and see if that helps
