Is it normal for the parking brake cable to rub against the back seat floor pans?
Thanks

 

No

 

Read each section of the accompanying diagram carefully noting specifically the location(s) of each piece of parking brake hardware. Zoom in on the image so it becomes more readable. Maybe print it out as you are under the car reviewing location(s) of each piece of hardware.
I have also included an image of the parking brake switch & pedal assembly. You may need to adjust the parking brake switch should you find you need to tighten the parking brake cable &/or re-route or replace any broken or suspect hardware.
Have you had the car into a service garage for any repairs e.g. exhaust, muffler, tail pipe(s), brakes, etc.? Often commonplace to find 'someone' moved/disconnected the parking brake cable & did not re-connect/re-assemble correctly.

 

I should mention perhaps a good place to examine 1st. Ensure the nuts which tighten & secure the equalizer are "tight".

 

Thanks, I'm reassembling the vehicle from a total teardown. I've searched online and seem a number of vehicles that have some rubbing of the cables on the underbody. I just dont see a way how to make it not rub (bummer cause I spent alot of time making it look clean!).

Let’s look at facts. GM Oldsmobile neither designed, produced or sold ANY vehicle in which parking cables rubbed against back seat floor pans. Something is incorrect in the configuration - either hardware or assembly. Are they the OEM original floor pans? A PO/Body shop or otherwise modify floor pans? On my phone cannot see the image in detail. Perhaps another member sees something straightaway. I’ll review the image later.

 

Dan - I haven't forgotten about you. I've been reviewing your image & spending time reviewing select parking brake routing diagrams from both 1969 & 1970. I can see where it's rubbing & I understand where it's rubbing. What would help is one or more images of the actual "routing" of the parking cable at each point from front to back i.e. each point where the cable is routed.

Is this the original parking cable which was on the car before tear down? Obviously, you're asking this question because it's rubbing. What isn't obvious is whether this cable was rubbing prior to the tear down or this rubbing is a new issue.
Was any parking brake hardware replaced (ordered new or used from another car) for this reassembly?
There are a fair number of parking brake cables depending on model & configuration e.g. wheelbase length & type of transmission installed.

I'm not completely familiar w/ the 1969 4-4-2.
Which transmission is installed in the car? TH350 or TH400?
Is the transmission manual or automatic?
I'm not familiar with the types of transmissions used in the 1969 4-4-2. Was there a long tail TH400 & a short tail TH400 - do you know, and if so, do you know which one is installed?

You'd think something as simple as a parking brake cable would be straight-forward & easy - but as stated, they made a fair number of cables, attendant hardware & variances in routing. Any references to 3539, 3639 & 4239 models (in the diagram) won't apply since none of those models pertain to a 4-4-2.

FYI - The parking cable routing is contained in the 1969 Chassis Service Manual. I don't own a 1969 Oldsmobile Chassis Service manual. Have you looked in the 1969 Chassis Service Manual (CSM).

 

EDIT: BTW, 35M38 references a TH350 transmission, 35M40 references a TH400 transmission.

 

The cables on my 67 rub on the floor the same as the OP whether right or wrong. In addition, I’ve had other Abodies do the same, I don’t worry about it.

 

Eric - Understand & it's likely a valid point. I've owned a '67, '71 & '72 A-Body - none of them rubbed.

 

I’ve had a number of “A” that I seem to remember the cables rubbing lightly on the floor, never considered it an in issue. HOWEVER, some of those had been changed or modified with trans swaps and accordingly cable swaps, but they were usually factory type, if not OE cables. A couple indeed had floor pans replaced or sectioned.

Its been so long since I’ve had an unmolested car I wouldn’t know what’s right or wrong regarding a detail like this.

Most of mine have some degree of rubbing. It's never been an issue.
