What is the benefit of inboard brakes?

Its main advantages are twofold: a reduction in the unsprung weight of the wheel hubs, as this no longer includes the brake discs and calipers; and braking torque is applied directly to the chassis, rather than being transferred to it through the suspension arms.

What effect does unsprung weight have on ride quality?

The irregularities of the road surface will transfer to the cabin through the suspension and hence ride quality and road noise are worse. For longer duration bumps that the wheels follow, greater unsprung mass causes more energy to be absorbed by the wheels and makes the ride worse.

Are brakes unsprung weight?

Unsprung weight is everything that is on the other side of the suspension. The wheels, brakes, control arms, wheel hub, and the rest of the goodies fall into this category.

What is a pinion brake?

A pinion brake is a special type of brake that will help your vehicle brake at a differential. Instead of using a master cylinder pushing fluid onto multiple cylinders in calipers and drums on all 4 corners of the vehicle.

What is a load sensing proportioning valve?

A load sensing proportioning valve system for the hydraulic brake system of passenger cars and the like for varying the amount of brake fluid pressure and thus the braking torque at the rear brakes of a passenger car.

How much unsprung weight makes a difference?

Unsprung weight has a huge effect on any vehicle’s acceleration, braking, and cornering abilities. It’s even said that at a drag strip, adding a single pound of unsprung weight to a car has the same effect as adding two or more pounds to the body. Check out the diagrams below to see why it makes such a big difference.

Why is less unsprung weight better?

Reducing unsprung weight is the key to improving handling. The lower the unsprung weight, the less work the shocks and springs have to do to keep the tires in contact with the road over bumpy surfaces. Lot of problems, if not all of them is caused by inertia. Bigger weight means higher inertia.

Are pinion brakes street legal?

Are Pinion Brakes Street Legal? No, in almost all states it is not legal to run only pinion brakes for your vehicle.

Is a brake proportioning valve necessary?

Yes. The addition of a proportioning valve is a must. Without it your braking system will not operate properly.

Does unsprung weight affect acceleration?

Unsprung weight has a huge effect on any vehicle’s acceleration, braking, and cornering abilities. It’s even said that at a drag strip, adding a single pound of unsprung weight to a car has the same effect as adding two or more pounds to the body.

What is a diff brake?

Definition of differential brake : a band brake acting on the difference of two motions or tensions and tending to be self-tightening when the rotating part turns in the normal direction.

What do pinion brakes do?

How does a brake load sensing valve work?

The shock absorber mounted on the control lever, together with the tension spring, takes up the dynamic impact caused by unevenness in the road. The load sensing valve operates statically, i.e. changes in the spring path which occur during braking do not change the control ratio.

What is the purpose of a load sensing proportioning valve?

Function and Purpose of the Proportioning Valve This valve is necessary for optimizing front-to-rear bias, also referred to as brake balance. It is a spring-loaded component that activates when fluid pressure builds when you step on the brake pedal.

What are the symptoms of a bad brake proportioning valve?

Since the proportioning valve decreases the pressure sent to the rear brakes, the main symptom the valve is going bad is the rear wheels locking up when the brakes are applied. Furthermore, the wheels will lock up more easily on wet surfaces. The rear brakes may feel touchy when applied even gently.

What is block brake?

Definition of block brake : a friction brake consisting of one or more shoes (such as wooden blocks) to be pressed against a wheel or other moving part.
