CSX4753 help with brakes

Engine oil and filter of course.

Good catch. I knew I missed an important part.

I have a CSX 47xx that I’ve owned for 20 years. I just rebuilt engine, carbs sent to Jim Ingese in FL, Brakes, recoated sidepipes, new tires, etc.



The brakes are Baer in my CSX4700 (are red with White Shelby lettering on the outside). If you need calipers mustang “R” front and corvette rear. ( ‘95 mustang “R” and ‘84 Corvette four piston).

The three reservoirs are Girling’s (two large are brakes and one small is clutch) need to be completely flushed if your car sat for awhile, as mine sat for a few years because of my issues. I had to replace with new Girling reservoirs (Finish. line) they are so thin that after many years they just don’t seal ( gasket disintegrated).

If your pads need to have a good brake-in, give it a hard drive and get them hot, someone told me once to ride them to get really good and hot.

I worked on a B&B with Ford brake a few years back and it would not stop. Well it did but took 200 - 300 ft. Scary!
I changed the brake fluid for Dot 3/4 synthetic. Then I could lock up the tires.

Dot 3 is fine doing a switch to 4, can make cottage cheese worse.

What Is Brake Fluid Made Of?
If you look at the chemistry behind most brake fluid, it comes from the combination of various types of glycols, which are basically a mixture of non-petroleum and other alcohol-based fluids. After a mixing process, the chemical name gets shortened to “polyglycol”. In addition, there are also high-grade silicone-based fluids, which cannot be mixed with any other type of fluid. So whether it's used in the brake or clutch system, it's important to understand the differences between these common types of brake fluid.

The brake fluid must maintain specific properties. Our brakes can get hot, sometimes up to 1200 degrees, so the fluid needs a high boiling point. Also, because our vehicles experience seasons just as we do, it’s important to have low freezing point as well. On top of maintaining both extremes, it's designed not to damage any rubber components in the brake system.

brake fluid properties
As a result, the chemical properties found in most brake fluids can permanently dull or damage paint. So be sure to handle with care and be quick to clean any accidental overspills. Brake fluid is hydroscopic, meaning it has a natural tendency to absorb moisture. And over enough time the added moisture can result in corrosion build up or a decreased boiling point. It’s never a bad idea to change your brake fluid every couple of years and try not to leave your reservoir cap off any longer than needed.

DOT 3 vs DOT 4
DOT 3

DOT 3 is the most common type of brake fluid used in domestic cars and trucks. According to the Society of Automotive Engineers (SAE), DOT 3 can absorb 2 percent of its volume in water every year. Over enough time excessive moisture will cause corrosion in the brake system which can lead to issues like vapor-lock or a spongy pedal.

DOT 4

DOT 4 is formulated for use by all vehicles, it has a higher boiling point than DOT 3 and it does not absorb moisture as fast. DOT 4 and DOT 3 are interchangeable, however it's best to avoid adding DOT 3 fluid to a system that already uses DOT 4. It's the preferred type of fluid used for street and high performance applications. Almost all of the brake fluids Speedway offers from Afco, Wilwood, and Ultra Lite will meet or exceed DOT 4 requirements.


I added the bold print so it would be easier for the speed readers

there is a 45 degree F difference in the boiling point of Dot 3 and 4.

Not enough to make any difference on a street car.

Thanks. What pads do they use? Mustang R and corvette (what year)?
