Hi Tiny86,
Lucky you! Put me on the list, too, for the next freebie... especially if they'll continue to pay for major parts and repairs while I drive it!
Geo is correct, the function of the parking brake is opposite of most modern ones. To set it, pull back the lever and then push in the button. To release, just pull back a little on the handle while not touching the button, and then let the handle go. This was done for racing - "standing start" road races and rallying - more common in Europe than in the US.
However, if the car has been sitting for a long time with the parking brake set there is a possiblity the brake shoes have "frozen" to the hub. Just backing off the adjuster might free them, or releasing the brake and rocking the car forward and back, or pressing on the brake pedal relatively hard a few times. If frozen, you'll need to get the shoes to release from the hub before it will be possible to pull the hub and inspect inside.
Sometimes drum brakes just stick or sometimes frozen brake shoes are a sign of a leaky slave cylinder. The fluid leaks onto the shoe lining, causing corrosion on the inside of the hub, which adheres the shoe to the hub.
If it's been sitting for a while, I'd strongly encourage a thorough check of all the braking system, front and rear, before taking the car on the road at all.
You might already know this and it sounds like you have a plan... After checking out the brake system, changing all the fluids and rubber parts such as hoses and belts are high priority bringing a "sleeper" back to life.
Sounds like your brother is helping with parts and info. Also, if he doesn't provide one, you might want to pick up a Service Manual for the car. There are some special maintenance considerations with older cars. For example, the gearbox fluid should not be modern GL5 gear oil. It will eventually damage the gearbox. GL4 is the right stuff, but is a bit harder to find.
By the way, you mentioned the car is a 1963. That might be true, or not. My 1964 TR4 was actually built in late 1962. It was common in the 1960s for car titles to relfect the year they were sold and licensed initially, rather than the actual build year.
This can be very important since some parts are different from year to year. There were changes to the suspension, engine and many other systems throughout production. When you go to buy parts, you'll need to refer to the car's chassis number.
That number also helps determine the actual year of manufacture. Tt's stamped on a plate under the hood, on the lefthand rear "shelf" (by the brake/clutch master cylinders and wiper motor). For example, my '62 is CT17602L. You'll find a similar number. Early cars only have the one number on the chassis plate, 1963-manufactured and later have a few more numbers indicating interior and exterior color codes.
The "L" at the end of the chassis just indicates the car is lefthand drive, built for export rather than sale in the UK. A TR4 built for sale in England or other parts of the UK where they drive "on the wrong side of the road" will have an "R" suffix after the chassis number.
Actually, the vast majority of TR4s were exported and relatively few (less than 2600 out of 40,000) were righthand drive and stayed in the UK.
One other thing about the chassis number, if there is an "O" at the end after the "L", it indicates the car originally had overdrive installed at the factory. It was also common for this to be added at the dealership, plus is a desirable option people still like to add, in which case the chassis number might not end in "O" even though the car has an overdrive.
FYI, the overdrive "switch" is a lever similar to the turn signal lever on the column, but on the righthand side of the column. When driving, pushing down on the lever will put the car in overdrive on 2nd, 3rd and 4th gears (some installations only operate overdrive on 3rd & 4th, but most TR4 overdrives work on all three). It's sort of like having 7 gears, but you can drive the car without using overdrive, if you wish, just shifting the 4 usual gears.
To give you some idea of when your car was built:
1961 - 2470 cars, approx. CT0001-CT2470
1962 - 15,933 cars, approx. CT2471-CT18404
1963 - 10,082 cars, approx. CT18405-CT28487
1964 - 11,518 cars, approx. CT28488-CT40006
1965 - only 250 TR4s were built, ending at CT40304, before the TR4A was introduced and the chassis numbers jumped to CT50001 (sequential thereafter, but sometimes using a different prefix: CTC to indicate independent rear suspension). Approx. 28,000 TR4A were built up through 1967.
Hey! Hot pink seat covers would be fine! It's your car, have fun! (But be aware that TR4s are increasing in value and originality is usually a big issue among buyers.)
Cheers!
