We have checked all the bulbs and replaced 2 of the same ones (one on each side as one looked dodge.All the other bulbs look fine,yet the icon still stays lit up when your foot is on the brake.I was told to replace them all at the same time perhaps!,or maybe is it a sensor and where is that!,its a 1995 Rav.

Im hearing the word replaced which is all good. But have you had someone stand behind the car with the lights turned on and also with foot on brake pedal!
If notdo that first before going any further.--if all the lights work then theres another issue -if not at least you have the culprit area

chrystalclear1, Nov 12, 7:47pm
well we did that and all the bulbs were fine except one that the filament looked at bit dodge so we just replaced the 2 of them,all the lights work fine.Can I be failed for a warrant for this warning icon staying on in the dash even if they all work!

Have you checked the fluid level in the brake fluid reservoir !

Arethe bulbs that you are replacing the correct voltage and wattage ! . its stamped into the ends of the bulbs.

High stop lamp is part of the same circuit and quite often I find them with 5 watt bulbs in them instead of 21 watt.

Though usually if the fluid level is low the light stays on until topped up, but the level may be such that a depression of the brake pedal is drawing sufficient fluid to cause the lamp to illuminate.

ok just going to check now.

kazbanz, Nov 12, 7:56pm
sorry--to clarify--You DID have someone check that all the three brake lights work and the two tailights and number plate lights work!-as in light up

chrystalclear1, Nov 12, 7:57pm
brake fluid level says minimum.so i may have to top it up to maximum!

therafter1, Nov 12, 7:59pm
That will be a good start.

mugenb20b, Nov 12, 8:00pm
What do you think!

chrystalclear1, Nov 12, 8:01pm
will go and get some brake fluid.was also thinking i wonder if its a sensor died or something!

mugenb20b, Nov 12, 8:03pm
No.and if your fluid level is at minimum, take your car to the garage on Monday morning to check for potential fluid leaks and brake linings.

Make sure you get the correct sort. DOT4 or DOT5.1 but NOT DOT5.

The fact the level is at the minimum suggests either 1) a leak or 2) worn brake pads on all brakes. There is one other likely option but it's difficult to explain.

In any case, it should be properly investigated.

kazbanz, Nov 12, 8:15pm
NO NO NO -- do NOT top it up to maximum. Show your poor mechanic some love and pour in enough to get the fluid level up to maximum of half way.
-Um just to explain. Something has caused the fluid level to drop to minimum
The USUAL cause is that the brake pads/shoes are worn out.if the resevoir is full its not a nice job taking fluid OUT -wjhich you would have to if all the pads are replaced.
If it is a leak somewhere then halfway is going to be enough to last untill monday when a mechanic can check it out for you

therafter1, Nov 12, 8:57pm
Not really no, we have a vacuum bleeder and you just remove the head fitting and dip the hose into the reservoir and vacuum all the old stuff out, then I let the fluid go at the bleed nipple when I push the calliper piston back in and after fitting the replacement pads I bleed the brakes to purge the brakes lines of any air that may have gotten into the lines as well as the old brake fluid in the lines, pump up the brakes with short pushes on the pedal and then re-check the reservoir level . it adds about 5 minutes to the job.

That's the correct way of replacing brake pads + bonus of having fresh brake fluid in the system.
