Brake Pedal Return

O.K., A-Body buds...

Here's the update on my brake pedal nightmare.

Took the car in for its appt. on the 9th.

The shop owner (Brakes & Alignment-only shop)
and his son spent over an hour on the car all together.

Ruled out any problem with the master cylinder, and/or its components.

(They had replaced the original MC w/a NAPA-Gold unit only 6 months ago, due to a leak. Vehicle only has 25K & has led an incredibly sheltered life.)

They said they didn't want to get the underdash brake pedal components dissassembled on a Friday afternoon w/o spare/replacement parts on hand, if needed. That was very understandable!

They seem to think a "return spring" (like the spring on a clothespin)
is broken, but could not locate an exploded-view diagram of the
underdash brake pedal assembly in any of their considerable references.

So, before making a follow-up appointment, I'll need to take them
the exploded-view illustration and have a source or supply of any
likely needed repair/replacement components.


**Can you guide me on how to locate such a pic, & a parts supplier?**

The car is parked until repaired, so your help is greatly appreciated!
