I think the most important thing to check is the brake fluid, as Hoygaard says. The handbrake warning light also doubles as a brake-fluid warning light. If this ever comes on while you're in motion you should stop pretty sharpish and make sure you're not low. (assuming you still can eek! wink )
If the light is staying on then your fluid has dropped suddenly or the switch is stuck which in this case sounds more likely. The light will usually flicker if the fluid is low or pads wearing, not stay on constantly (unless there has been a sudden loss).
sorry to mention this here, but the same thing is happening on my brother's car. the handbrake light comes on while cornering.
but the fluid is ok, and the front pads are ok too.
could the rear shoes be wearing?
I had this also... cured it by connecting the 'flying leads' for the wear sensors on the front pads to the pads. They were left loose by the last punter who changed the pads and were hitting off the chassis giving a false brake wear warning... The often break off anyway...
Okay, I got it sorted; or so I thought. After reading Hoygaards message I checked my fluid levels and behold the mysterious land of Alfas the fluid was low (I'd only checked it a couple of weeks prior!!) and so duely topped it up.
So what am I complaining about again for? Because it bl00dy well happened again today!! I looked under me hood and what did I see? Low levels!!! Low bloody levels? I only topped it up a little while ago....somethings afoot I fear!!
Any ideas? (don't say it's leaking from somewhere cos that's too bl00dy obvious!!) Anyone have a leak before or knows of a weakness? Are the pipes exposed under the car or something? Help me out here....I'm a desperate man!!!!
just a thought - about 6 weeks ago i got the hand brake light treatment - i topped it up and it sayed off. I couldn't find any evidence of leaks at the time.
then my clutch slave cylinder went 2 days ago,
I wonder if the leak was in the slave cylinder, the rubber boot would probably contain it a bit until the whole thing gave up. I guess the same could apply on the clutch pump.
