Posted October 2, 20186 yr comment_558637 My ebrake light shows a little dim on the speedometer when the ebrake is off. Where should i check? It must be a bad ground somewhere.

October 2, 20186 yr comment_558655 My guess would be that there is nothing electrical wrong with your e-brake light. There is a little rubber shroud inside the speedo that is supposed to separate the e-brake light from the dash illumination lighting, and I suspect what you're seeing in your e-brake light is bleed over from your dash illumination bulbs. The rubber shroud gets dry and brittle over time and maybe yours has deteriorated to the point where it's not sealing properly and it's allowing light to get where it doesn't belong. That combined with the fact that your speedo lights are very very very very very cornea burning bright.... So... Does the e-brake light glow go away when you turn off the dash illumination bulbs?

October 2, 20186 yr Author comment_558657 If i turn the dashlights off you can still notice the ebrake light dim on the speedometer. Link to comment https://www.classiczcars.com/forums/topic/60847-e-brake-light-dim-on-speedometer/#findComment-558657 Share on other sites More sharing options...
October 2, 20186 yr comment_558667 Oh. In that case, forget about what I said. If it's still glowing even with the dash lights completely off, it's not light bleed.

October 2, 20186 yr Author comment_558672 Could it be a bad ground or should i also check the brake proportioning valve? Link to comment https://www.classiczcars.com/forums/topic/60847-e-brake-light-dim-on-speedometer/#findComment-558672 Share on other sites More sharing options...
October 3, 20186 yr comment_558717 Could be a grounding issue or a faulty proportioning valve. Or a faulty parking brake switch. Why does it look like it's only lighting up half the "BRAKE" letters on the speedo? Like light is bleeding through from the left side. Or the bulb isn't inserted into the hole in the back of the speedo completely? Even if it's dim, I would expect it to light up the whole "BRAKE" indicator evenly. Have you stuck a hand up there behind the speedo and gently wiggled stuff around to see what happens?

October 3, 20186 yr Author comment_558743 I will stick the hand in. I have never done this as this bulbs were replaced by the shop that installed the Air Conditioner when the dash was outside the car and i guees it was easier then. I simply hope not to break any wire , contact or the bulb when wiggling it. What would be your careful approach to this?

October 4, 20186 yr Author comment_558799 Jajajaja i discovered that by removing the female plug from the proportionate valve under the brake booster the ebrake light on the speedometer did not appear at all.

October 4, 20186 yr comment_558803 That most likely means you have problems with your brakes. One circuit is probably not working. Are your stopping distances longer than you think they should be?
