How can I check the condition or quality of the brake fluid? How can I tell if it's good or need to be flushed and changed?
You can usually tell if the brake fluid is too dirty or contaminated through its color. If the brake fluid has turned darker or appears black, this fluid needs to be changed. You could still conduct some tests, though. For further testing, you may use some tools. A chemical test trip can be used to check for the presence of cooper in the fluid. If there's a high level of copper in the fluid, it means that the corrosion inhibitors have broken down, which happens when the brake fluid gets old. You can also test for moisture in the fluid. An optical refractometer can be the best tool for this. If there's high moisture content, then it may be time to flush the system and change the fluid since moisture can dilute the fluid and make it less effective. If you don't change the fluid, some brake system parts may corrode. The boiling point of the fluid can also go lower with the presence of water. To check the fluid's boiling point, an electronic tester may be used. Refer to the label or manual for the dry boiling point and wet boiling point of the fluid. If the boiling point drops significantly, the fluid will be less effective.
How can you tell if the transmission of your vehicle is failing or having some issues?
Gear shifting should be smooth. If there's some hesitation, then that means that something's not right with your vehicle transmission. In manual transmission, the engine may rev up but the car may not move just as quickly. In which case, you have to look for a busted clutch or consider some other transmission issues. Lack or delayed response can be noticed on automatic transmission as well, but this can be tracked or detected when the car is in drive or in park. You'll have to check the assembly to figure out the problem. Don't take this problem lightly. It's not just about smooth gear shifts but also your safety.
What are the signs of a failing alternator? I'm not sure if I already have to replace the alternator of my Ferrari Mondial. The battery is fully charged, but I'm still having trouble starting the vehicle.
Make sure that the auto battery has enough charge. If the battery is fully charged but the vehicle still won't start, the problem may lie with the alternator. Have the charging system of the vehicle checked. If the alternator is already failing, the lights of the vehicle may become dim. Power windows and other electrical components may also operate at a slower pace. You may also notice some grinding or whining noise coming from the alternator. Also watch out for a burning rubber smell, which could be coming from a slipping belt on the alternator pulley. Run some checks on the vehicle's electrical system. Also inspect the belt to see if it's too tight or loose or already cracked.
