Is it safe to drive when there is a leak in the vacuum of the brake servo?

Generally no

Do the brakes still work without the servo?

There are several types of brake servo and are we talking about unbolting it and throwing it away or do you mean if the servo is eleminated from the system? Most brake systems will work if the Brake Booster servo does not work. No braking system will work if you unbolt the servo and throw it away.

What would be the first thing to check if the cruise control on a 90 riveria doesnt work?

What would cause a 2001 Dodge Ram 2500 with the diesel engine cruise control to not set but the green light comes on when I hit on-off button?

who ever said that a dodge ram diesel does not have a servo it is not true. I have a dodge diesel 2001 and it has a servo and the answer to this question is it had a vacuum leak in the servo vacuum line, changed that and cruise control worked great. the servo is under the drivers side battery.

Where is the fuse for the cruise control on a 2000 dodge durango?

There isn't an individual fuse. It is run by the engine computer. Check the vacuum line running from the intake to the cruise servo.There isn't an individual fuse. It is run by the engine computer. Check the vacuum line running from the intake to the cruise servo.

How do servo motors alter the RPM?

servo motors change their rpm as instructed servo motors recieve instructions from a controller to do some action servo motors generally have feedback so the controller can see where they need to go servo motors can be electric air or hydrolic powered an example: cars have a cruse control you set a desired speed of travel the vacuum powered servo motor controls the throttle of the gas engine the transmission controls the ratio of gearing so the engine is not overloaded at some point when conditions are satisified you will get the correct speed ... if you go over the desired speed the vacuum powered servo motor backs off which eventually controls the differential driving rpm of the rear wheels here again the servo motor can be considered to be the valve on the vacuum bladder or the entire drive train

Purpose of brake servo?

The purpose of the brake servo is to provide power assistance to the braking system when then brake pedal is pushed. The brake servo is usually a flat drum-shaped unit to the rear of the brake master cylinder. Typically, on a petrol car, a hard plastic pipe connects the servo to the inlet manifold of the engine. When the engine is running, air is sucked in through the inlet manifold; this partial vacuum is stored in the servo drum, and is used to amplify the pressure exerted by the driver on the brake pedal. A one-way valve is fitted in the system, usually in the plastic pipe, to avoid the vacuum in the servo being lost when the throttle is opened or the engine switched off. With a diesel engine, insufficient vacuum is generated in the inlet manifold to work the servo, so on diesel cars the hard plastic pipe from the servo is connected to a vacuum pump, which is typically mounted on the end of the camshaft, or sometimes on the back of the alternator. The symptoms of brake servo malfunction are usually a brake pedal that feels very stiff and has to be pushed very hard to operate the brakes. One common cause is the plastic pipe split or leaking where it joins the servo or the inlet manifold. The one-way valve can also fail, as can (less commonly I would say) the servo unit itself. On diesel cars, the vacuum pump can fail or can be tired, causing the pedal to stiffen with repeated use of the brakes. Good luck from Norn Irn!

What would cause the Cruise Control Light to come on but not activate the Cruise Control on a 2001 Dodge Ram 1500 V6?

Leak in vacuum line to cruise control servo (actuator). Most commonly caused by vacuum line being inadvertently bumped & disconnected while someone is working under the hood or there may be a crack in the line. Another possibility is a bad servo. I believe the servo is located in the space between the battery and radiator (not sure on this because I have a 2001 Dodge Ram 2500 with the diesel engine which does not use a servo for the cruise control.) Once you locate your servo, follow the vacuum line from it & check for cracks. Yet another possibility is the servo cable may be disconnected from the throttle body.

How would you check that a hydraulic braking system vacuum servo is assisting foot brake pedal effort?

If a vacuum servo is fitted, then with the engine off, totally deplete the stored vacuum by repeatedly applying the service brake. Fully apply the brake and hold at a constant pressure. Note whether the pedal can be felt to travel further when the engine is started.

What do a servo do for merecedes Benz 190-e?

A servo helps by way suction power or vacuum power from the engine to be utilized to help a driver stop his vehicle with less brake effort. Without this servo a driver would need lot more effort to brake and more so in a downhill drive.

What is a Micro Servo?

A micro servo is a small servo. The term can be used to describe any servo that is smaller than a "typical" servo. For example a servo that is about 1.5" x 1.5" x 0.5" would probably be called a micro servo. Most servos use the same signals and voltages, so usually a micro servo can be plugged into any servo controller or radio receiver that a regular servo can be plugged into.

Can drum brakes be servo or non servo?

They are either servo type or non servo type, they can't be both types.

Why Engine stops running while breaking?

If the engine is cutting out when you press the brake pedal This is indicating a servo or vacuum leak to the servo which will weaken the air/fuel mixture to the extent that the car will not run I hope this post is of use to you best wishes

How are vacuum lines run to and from?

Vehicles made in the USA have a diagram on a sticker located under the hood in the engine compartment. The sticker shows the routing of the emission related vacuum lines. Vacuum lines ae connected to the inlet manifold at one end, to work on the depression at this point. There are several ancilliaries that may work off this, the most popular being the brake servo. Also sensors for the ignition (advance and retard), vacuum servos for 4x4 control, computer management box and emmision controls.

Why does a diesel engine not produce enough vacuum?

As a diesel engine does not have a throttle valve in the air intake, no useable depression is created in the intake manifold. That is why diesel engines are fitted with vacuum pumps to operate the brake servo.
