Another job last night. The brake lights weren't working and also noticed there was over an inch of freeplay in the brake pedal. I got under the dash and disconnected one of the brake switch wires, copping a load of brown, southwest, country road dust in both eyes. I cleaned the terminals and did the other one. Being very clever, I shut my eyes this time
The lights worked now, but not until the brake pedal was pressed a fair way, so I thought I'd adjust the freeplay first. I adjusted until I got somewhere between almost no freeplay and 1/4". As per normal, I read the repair manual AFTER I'd adjusted and found it should be 1/8" - close enough. There's almost no adjustment left now - is that normal?
Now there wasn't enough adjustment in the brake switch to make it contact when it should. I thought about bending the bracket, then decided instead to modify the switch with the bench grinder - probably removed about 3/8" all up.
I adjusted until the switch activates just after the freeplay takes up.
May be an original switch - Delco Remy written on it.
Now brakes and brake lights are all good. The previous owner told me he'd replaced or had serviced the brake components about 18 months ago, including cylinders, flexible lines and all but two hard lines. They seem fine whilst driving.
bloody nice John. Looks to be in fair to reasonable condition
