Handbrake warning light

Recommended Posts

Hi all, the handbrake on warning light comes on intermittently on my t25, the handbrake does need adjusting, could that be it?

Hi Thom .Not being sure of your mechanical knowledge please excuse if you know  this. Under the cowling over the handbrake lies the switch,I think, which puts the brake warning light on I would check here first. With regard to the handbrake adjustment I would first see if the brakes can be adjusted at the wheels first as this  as this is where the wear takes place. The cable is unlikely to stretch if the handbrake is not pulled up too tightly

Unlikely that the amount of travel on the handbrake lever would trigger a false warning light, but it could be a faulty or misaligned switch as per Crofter's advice above.  The switch should bring the light on when the handbrake lever is lifted sufficiently, and should go off again when the lever is placed back 'home'.

The handbrake warning light (on most cars) also comes on if the brake fluid level is low.  The level could be low if either/both the front/rear pads are worn, thus the pistons are at their outer end of travel, thus 'using' more fluid.  The T25 Avensis (2003-2008 model) has handbrake drums/shoes built into the inside of the rear discs, and they are adjusted like 'normal' brake shoes, ie by turning the adjuster.  The shoes don't really wear down much since they're only used to hold the car once stopped, not like a normal brake shoe which would wear down by use when actually braking.

You can access the adjuster wheel through the hole of a removed wheel nut, I can't remember wherabouts the adjusters are (it's been a while), but if you shine a small torch into the hole you should see it as you spin the wheel.  Bear in mind they're in mirror positions each side of the car, ie if one side is at 4 o'clock the opposite side will be at 8 o'clock etc.

Thanks for the advice guys, bit of detective work to or I think!
