Question HELP!: Adding Brake Fluid!

I have a 2000 v40. The brake light came on yesterday, and the brake pedal went soft. I'm assuming I can get away with just adding brake fluid for now, (at least to get it to the shop), but I can't get the cap off. I'm afraid that if I twist it too hard, I will break the bottom where the plastic reservoir connects to metal. Any tips???? The manual says to always have the brake fluid added/flushed by a dealer, but this seems like a ripoff.

I would say you have a leak somewhere. Check all your pipes and unions for fluid loss and if you are not sure take it to a garage. Don't take any risks with the brake system.

Yeah, but I still need to get it two miles. I need to at least add enough fluid to get it there.

Hold the reservoir bit with the other hand, use a strap wrench on the cap, it will come off without snapping IF you hold the bottom part. you should be able to see the level without taking the cap off.
is your car a manual gearbox? if so the clutch shares that fluid res, so it may not be a brake issue but a clutch master / slave cylinder one, either way you probably need to check the level and top up..

If throwout bearing on your clutch is leaking, you should get the servide done ASAP. If not, brake fluid comes on dual mass flywheel and destroys it - rubber between both disk parts.

It happened on our VW Transporter T5, authorised dealer mechanics changed the clutch plate, but not the throwout bearing. Even if it is clearly stated from factory that whole parts on the list must be changed. 40.000 km later, everything between engine and transmission gets ****ed with fluid. And there goes your hard earned 700 € down the toilet.

Automatic trans, but thank you. It seems that it just had air in the system. Maybe there is a leak where it's taking air in. Got to go have it bled and checked.
