John, Simon has a great photo! Take care and inspect the "L" shaped metal pipe. These will deteriorate where the hose attaches off to the right, may need to replace this too.
Are you refering to the thermostat for the coolant system on the engine or the controls for the in car heat? One can affect the other. In car heat is usually controlled by electronic within the dashboard.
The engine thermostat is located below a black L shaped pipe on the front end of the engine. Refer to the photo below.

It's very possible to be the master cylinder, the o-rings on the piston could be worn, letting the fluid seep back through instead of getting full pressure through the lines. Could also be the brake booster.
Try changing the master cylinder first, which is cheaper and easier, and see if there is a difference, you'll need to bleed the brakes again.
To check the booster,
With the engine off, pump the brakes until the pedal is hard, then hold pressure on the brake pedal and listen for air escaping, or the pedal goes slowly to the floor, Do that after the master cylinder has been changed, at least that will be eliminated.
Testimonial: "Hadn't thought about the O-rings on the rod thanks for the idea. Great Idea Thanks!"
SOURCE: orifice tube location on a 1995 gmc jimmy
it is located in the high pressure AC line at the AC evaporator core inlet. The high pressure line is the smaller of the two AC lines that come from the AC compressor on the engine..
