      I have an Alpine series V, which I recently inherited. It has been driven very little the past few years. Around two weeks ago I took the Alpine for a short spin and the brakes stuck on partially after coming to a stop. The car was still drivable. Initially, I was thinking the brake stick was due to corrosion in the calipers. But this seems to be a problem only when the engine is warm. Last night I idled the engine to warm it up and the brake lights came on by themselves. The brake lights are controlled by brake fluid pressure not brake pedal position, right? Any pointers for what steps to perform to resolve this would be appreciated.

      Are you still using a brake booster? Sounds like the
      seal in the plunger inside the canister is hanging up.
      Could also be the vacuum valve in the booster is
      leaking air to the can and applying the brake.

      Remove the booster and and install a brake booster
      bypass. Its usually two unions and a short 4 inch
      brake line with the proper ends. Be careful and
      you may only have to bleed at the last union.

      Now drive the car. You’ll have to push the pedal a
      bit harder. If the brakes work fine, your problem
      is in the booster. Most race car drivers race their
      Alpines and Tigers without the booster. They are
      just too unreliable.

      If the brake problem persists, you’ll have to think
      about (1) a weak pedal return spring or (2) A weak
      or broken spring in the master cylinder.

      The brake light switch is hydraulic and notorious
      for failing or no turning the brake lights on unless
      you push hard on the pedal. Easy stop can lead
      to some idiot running into you.

      Go to and look up how
      to replace that switch with a modern electrical
      switch. A worthy modification.

      Leave that booster off (or install just for looks)….to improve pedal power without booster switch to a smaller bore master cyl. Early Alpines have a smaller bore than later series, some owners use datsun dual MC set-up…also check out…….later Alpines use a 7/8 , early is 3/4 I think…….Mike in Florida
