How it's done: 1  Inspect rear wheel cylinders for leakage. 2  Inspect rear brake shoes and hardware. 3  Replace wheel cylinders if found faulty. 4  Adjust rear brakes. 5  Lube backing plate. 6  Make sure axle seals are not leaking into brake drums. 7  Bleed entire brake system. 8  Perform a brake inspection, including test drive.
The bottom number, called the diastolic pressure, is the measurement as the heart relaxes between beats. Normal blood pressure is a systolic pressure of less than 120 millimeters of mercury (mm Hg) and a diastolic pressure of less than 80 mm Hg, or 120/80 mm Hg, according to the American Heart Association (AHA).Having a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension.A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.aving a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension. A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.
Now a blood pressure of 120/80 is considered normal, and blood pressure readings of 130â139 are considered pre-hypertension. Readings above 140/90 are considered high blood pressure, and the current thinking is that anyone falling into this category should be taking medication to lower blood pressure.urrently the textbook definition of normal blood pressure is 120/80 mmHg. But the definition of normal has changed over the years. At one time, it was believed that normal systolic blood pressure was 100 plus your age. In the 1970s, intervention wasn't even recommended until pressures exceeded 165/95.
