Frequently asked questions about Hydraulic Brakes
1. What modifications do I need to perform on my Model A to put on hydraulic brakes?
Ans. None if you use CLING'S brake system.
2. Can I use my Model A backing plates, hubs and brake drums?
Ans. No! You use 1939-1948 Ford backing plates and 1940-1948 hubs and drums.
3. Will my Model A wheels fit the 1939-1948 hydraulic brake drums?
Ans. Yes with one exception. The 1939 brake drums have a larger bolt pattern and will not fit Model A wheels.
4. What type of brake fluid is recommended?
Ans. Use a good grade of brake fluid.
5. How long can I store brake fluid?
Ans. Never store brake fluid because moisture accumulates in opened cans and moisture KILLS brake fluid.
6. I have an old brake system. What do I use to flush out the old brake fluid?
Ans. Denatured Alchohol.
7. What's wrong when I have squeaking brakes?
Ans. Squeaking is a vibration with drum brakes generally caused by sharp edges on brake shoes and not enough tension
on spring clips or return springs.
8. Should there be free play at the Master Cylinder push rod?
Ans. There must be free play on the push rod of the master cylinder.
If there is no free play, the piston in the cylinder will not return to its home position, therefore causing the brake system to be engaged at all times.
Each time you push on the brake pedal it puts a little more pressure on the system, which will cause the brakes to drag, get hot and eventually lock up.
Check to see if the return spring is pulling the brake pedal to its home position thus not allowing the internal Master Cylinder spring to do all the work.
9. What sequence do I use to bleed the hydraulic brake system?
Ans. Bleed the master cylinder first then go to the longest line from the master cylinder working to the shortest line.
10. Brake pedal does not hold after bleeding brakes.
Ans. The solution is a process of elimination to figure where the problem is. Disconnect the Master Cylinder and plug the outlet port. Bleed the Master Cylinder.
If after bleeding the Master Cylinder the pedal stays up and hard then you know the problem is with one of your wheel cylinders or a leaking line or fitting.
NOTE: I have seen new Master Cylinders and wheel cylinders be bad.
FORD V8 Transmission 1932-1939
1. Will CLING'S V8 master cylinder adapter fit 4-cylinder transmission?
2. How can I tell if I have V8 or 4-cylinder transmission?
Ans. THe quickest way is to look for the oil fill plug. V8's fill plug is on the passenger's side of transmission while 4-cylinder fill plug is on the driver's side.
3. V8 Transmission Hardware needed for this conversion.
Ans. Use throw out fork, throw out bearing sleeve & rear u-joint housing from V8 transmission.
NOTE: Use Model A or V8 throw out bearing.
Serpentine Pulley System
1. Why are the blades on the fan unevenly spaced?
Ans. The fan blades are unevenly spaced for balance and elimination of harmonic vibration. All quality fans have this feature.
2. Are there any modifications to putting Serpentine pulley system on my Model A?
Ans. No modifications are required.
3. How do you get such a horsepower increase switching from V belt to Serpentine belt system?
Ans. The Serpentine Pulley System has smaller driving grooves that create greater gripping, less friction and less heat.
