How much brake pressure is normal?
Most of the metal brake lines burst around 15,000 psi. The typical full-lock operating pressures are 900–1,000psi (69 bar) with manual brakes and 1,400-pluspsi ( 96 bar) with power-assisted brakes.
How much pressure should my brake pedal have?
The average driver comfortably generates a peak of 70 pounds of force on the rubber pad at the end of the brake pedal during a moderate stop. The brake pedal is nothing more than a mechanical lever that amplifies the force of the driver.
How do you increase brake pressure?
1) Line pressure can only be increased by either increasing the mechanical pedal ratio or by decreasing the master cylinder diameter. In either case the pedal travel will be increased. 2) Clamping force can only be increased either by increasing the line pressure or by increasing the diameter of the caliper piston(s).
What is the primary reason for brake pedal fade?
Brake Fluid Fade: Brake fluid fade can happen when water in the vehicle’s brake fluid overheats from all the friction. That overheated water boils into steam, which reduces the effectiveness of your brakes. When brake fluid fade occurs, pressing down on the brake pedal may result in a soft or “spongy” feeling.
How big are the brakes on a Volvo 240?
REAR: 9.6 mm thick solid rotor. 281 mm diameter. PN 270736-2. Volvo 240 Master Cylinder: M10 x 1.0 bubble flare brake line union ports. Non-ABS master cylinder has STEPPED bores: 22.3 mm primary (rear bore), 15.75 mm secondary (front bore). ABS master cylinder has STEPPED bores: 22.3 mm primary (rear bore), 19 mm secondary (front bore).
What to do about bleeding brakes on Volvo 240?
I put in a new master cylinder, and attempted to bleed the brakes, but the pedal is still soft. Bled it again, same outcome. These two times were with an assistant doing the pumping and holding. Read online to try drive it a bit, maybe it’ll dislodge an air bubble so I did that.
Are there any problems with the Volvo 240?
It commonly fails in the open position allowing super heated air to be drawn into the engine, which reduces performance as well as dramatically shortening the life of the expensive air mass meter. The seats in the 240 are very comfortable when they are in good condition. 240 seats offer excellent adjustable lumbar back support.
Are there any problems with the Volvo system?
Volvo has had problems with this system since it was introduced in 1976. Volvo’s still run into the same issues on their newer models. Possibly in theory Volvos system is better, but in reality it gets overlooked and inevitably becomes clogged up and causes oil leaks and idle problems.
