For over 3 months the dash board brake warning light on my 1997 2.2 Toyota Camry Auto has come on intermittently - sometimes not for 2-3 days then 2-4 times in an hour but always goes out after a few minutes. This is the same panel light as for the handbrake. The brakes are working 100%. I have replaced both bulbs in the tail cluster.

How can I fix this OR disable this feature without also affecting the working of the hand brake warning light?

Many thanks
