Brake warning light?

[AeroNut]

Prob' a silly question.....
The brake warning light comes on every now and then? Is this a sign of low fluid, low pads or something else....... Cos nothing looks wrong!

Could be both...... as Low pads = drop in brake fluid level.... as it's a now and then( e.g hills) sounds like low fluid...... It is really a weekly underbonnet check like, Oil, coolant and washer bottle..... but often gets missed....

I've just been having this - brake light coming on when I'm on a steep slope or under heavy cornering etc.

Accompanied by a faint but noticeable and slightly annoying scraping noise, normally under braking.

I knew from my last MOT my rear discs were a bit on the thin side, but on checking them was a wee bit surprised to see that my rear pads were very thin. Only a year old too, so they must have been cheap ones!

The pad wear indicator is a wee strip of steel that scrapes on the disc when they are low enough - hence the annoying noise.

When I replaced the rear discs and pads, I found the pistons were very far out indeed. Surprised that one hadn't popped right out.

Simple enough job to do though. Details are in the wiki for pads and discs.

Fronts are similar to do.
