Q: Brake light comes on.

asked by on November 24, 2016

1999 Nissan homey engine is a qd32 3.2ltr non turbo diesel. My problem is when the brake is pressed hard or 2 or 3 Times quickly the handbrake light (!) Comes on. I've bleed the brakes and changed the fluid and checked for leaks all is good. I've disconnected the handbrake sensor, it's not that. I've disconnected the vacuum sensor and it stops. So it must be the vacuum. The brakes work really well and so does the a.c..the van has no mechanical problems. the brakes have to be pressed harderor more times the higher the revs in order to get the light back on. At idle just 2 or 3 Times but 5 or 6 at higher revs. I hope this makes sense.
My car has a manual transmission.

Hi there. Check the distributor or coil packs to the vehicle. The surging would most likely be caused by the electronics getting old and causing a delay in the spark ignition. I recommend replacing the spark plugs (https://www.yourmechanic.com/services/spark-plugs-replacement) and wires...
