2003 Toyota Solara Parking Brake Light & 1972 Chevy K10 Pickup Vacuum Diagrams

Jan 22, 2007 Vincent Ciulla

2003 Toyota Solara with a flickering parking brake light and a 1972 Chevy K10 Pickup that's looking for some vacuum diagrams.

Question: Toyota Solara Parking Brake Light

Vince: I have 2003 Toyota Solara, the parking brake light comes on intermittently and I would like to fix it. I assume the switch assembly needs adjustment. Do you know where I can find some instructions on where the switch is and how to access it?

Thank you,

Michael

Answer:

What you have to do is remove the center console. Once it's off you will be able to see the parking brake switch mounted on the base of the parking brake handle sub-assembly. Before you go through all of that, check the brake fluid level since low brake fluid will also cause that light to come on.

Question: Chevy K10 Pickup Vacuum Diagrams

Vincent, I have a 1972 Chevy K10 Pickup that I purchased from the original owner in 1997. It has a 350 V-8 engine and a QuadraJet carburetor. I have added an HEI distributor with vacuum advance. After two years of trying to tune-up the engine, I discovered that the distributor was retarding the timing, not advancing the timing. It was a bad part straight from the GM parts department.

My brothers and I checked every system; ignition, fuel pump, etc. until we narrowed it down to the real problem. One question that came to mind was the vacuum routing. The old cars and trucks did not have it shown on the emissions label and there are no clear pictures in the service or assembly manuals.

Is there somewhere to find illustrations of the vacuum hose routings? If not, are there general rules for where vacuum lines get connected, like what gets manifold vacuum vs. what is connected to the carburetor?

Answer:

The only place I know of that would have those diagrams would be in the reference section of the public library, all the other sources I have access to don't even go that far back. As for a general rule of thumb, it depends on the device. If it needs vacuum at idle, it should get manifold Vacuum. If it needs vacuum at speed it should be connected to ported vacuum. Now this is a very general rule. There are vacuum switches that provide vacuum to a device when the engine is cold or hot. There are ported vacuum switches that themselves can be vacuum or electrically controlled to provide vacuum under different engine loads.
