Brake Ligth Flicker

The brake light in my 90 has been flickering lately. I think I need pads. Does this thing actually serve as a warning light?

I think it did on some of the Range Rovers and Discos. Mine would blink when my fluid level would get low,I am not sure of the differences between the 90 and the 110..

Pads wear, which makes the pistons extend out further which drops the fluid level which triggers the light. Check your pads to see how low they are. There are not sensors on the pads.

Or you just need to add brake fluid. If its already at the FULL line, Fill it a little above the FULL mark on the reservoir and see if it goes away.

I figured I needed pads.

So annoying. More money to spend

Be sure to clean the two little brass plugs and ring that is in the cap of the break reserve. If they are corroded then your light will flicker.

Could the flicker be from a short in the wiring?
Same thing just started happening to me. I had my front brakes replaced less than 1000 miles ago.

Yeah I have heard it could be that too. At last check I was at 40% front and 30% rear or something like that so I assumed I was due.

There is another thread titled something like "should I be worried"
discusses removing the emergency brake boot and cleaning the wires.

I'm going to check that as soon as I can get home before dark or this weekend. It's annoying but dealable till then

That happened to me and all that was wrong is that I was low on brake fluid. I topped it off and the light went off.

Okay

I'll check the brake fluid level also.
Looking at other threads on brake fluid says to use Catrol GT LMA (Should have a minimum boiling point of 500 degrees F.)

If I can't find that, will any DOT4 with minimum boiling point brake fluid suffice?
How can I tell if what's in my D90 is mineral oil or synthetic?

Thanks in advance.

Trouble is, when "topping up" the brake fluid, when you come to change the pads and push the pistons back in.....


....all the extra fluid overflows from the reservoir over your paint.

far better to check the pads first.
