How do I drain brake fluid in 2006 dodge sprinter: Altering your Sprinter van’s brake fluid commonly helps keep your van’s stopping energy. Brake fluid is hygroscopic, which implies that it absorbs water from the environment over time. Water will corrode the brake strains and calipers from the within, however it should additionally decrease the boiling level of the brake fluid, which has a adverse impact on braking power. The method of changing the fluid in your brake system is usually often called “bleeding brakes.”
Bleeding the brakes may be very simple in a Sprinter Van – all the things may be very accessible and also you don’t even have to raise the truck. However should you’re not helpful with instruments, it’s greatest to have knowledgeable change your brake fluid for you.
For those who change the brake fluid your self, you’ll need to take away the outdated fluid first, then fill the system with the brand new brake fluid. I discover it a lot simpler to make use of a strain bleeder; there may be additionally one other option to bleed the brakes, nevertheless it requires a second particular person
BLEEDING THE BRAKES ON A SPRINTER VAN
The strain bleeder is principally the identical factor you’re most likely accustomed to from spraying insect repellent in your yard. It’s merely a bottle that has a pump to generate strain. As an alternative of a sprig wand, it has an adapter that threads into the brake fluid reservoir.
Join the facility bleeder to the reservoir and pump to construct some strain. Don’t apply an excessive amount of strain as this can destroy your reservoir at greatest. At worst, it creates leaks within the brake system elsewhere. The Sprinter service handbook says that 15 to twenty psi is ample; Personally, I don’t go above 10 psi. It could take a number of extra minutes, however I may be certain nothing snaps open.
Earlier than continuing to the subsequent step, be certain the truck can’t roll! Put it in park in case you have an computerized transmission or in first gear in case you have a handbook. Set the parking brake and ideally use some wood blocks on the back and front of 1 wheel to cease the truck from shifting.
Now, with strain within the brake system, you’ll have to bleed the brakes to get the outdated fluid out. On every brake caliper you’ll find a bleed screw. It’s lined with a rubber plug to guard it from street mud clogging the bleeder screw. Begin with the brake caliper that’s furthest from the brake reservoir (on a Sprinter van, the rear passenger wheel). Take away this plug and join a small hose to the bleeder screw (it helps to lubricate the screw a bit to get the hose over).
The opposite finish of the hose goes right into a vented bottle. You should purchase purge bottles, however you actually solely want a soda bottle with two holes within the cap. By means of a gap within the lid passes the hose from the bleed screw to the underside of the bottle. The opposite gap goes by way of one other hose that acts as a vent, this one doesn’t go all the way in which to the underside of the bottle, you don’t need the liquid again out of it. Solely the air that’s within the bottle.
Now, with the hose connected, open the bleed screw – it’s a standard thread, so the left free opens it. Simply twist it yet another time, you will notice the fluid popping out of the hose. You don’t need fluid popping out of the threads. When you don’t see any extra fluid popping out of this caliper, merely aerate, shut the screw and transfer on to the subsequent caliper, going from the caliper farthest to the one closest to the brake reservoir (driver rear, passenger entrance , entrance of the motive force).
Now that the brake system is empty, you possibly can fill it with contemporary fluid. Take away the facility bleeder and fill the reservoir to the brim with brake fluid. Join the strain bottle and apply strain to the system.
Once more begin with the caliper with the best distance to the tank, join the bleeder hose and open the bleeder screw. This time you anticipate fluid to return out of the hose and solely fluid. For those who nonetheless see air bubbles within the hose, proceed bleeding the caliper. Any air left within the system may have a adverse impression on braking power. If you find yourself finished with a gauge, shut the bleed screw rigorously; you don’t wish to overtighten it and strip the thread. Proceed with the remaining three calipers.
Additionally be certain the reservoir is all the time full – if it stays empty you’re pumping air again into the system and you’ll have to begin over to take away all air bubbles.
As soon as you’re finished with all 4 calipers, be certain the brake fluid within the reservoir is between the MIN and MAX marks and shut the reservoir with the unique cap. Watch out when driving the van for the primary time after bleeding the brakes. Press the brake pedal a number of occasions earlier than you begin driving, and ensure there is no such thing as a site visitors round you while you take a look at the brakes.
And eventually, the helper-requiring handbook bleed process as outlined within the service handbook, should you actually don’t wish to purchase a strain bleeder:
Take away the reservoir filler cap and fill the reservoir.
If the calipers or wheel cylinders have been serviced, open all of the bleed screws on the calipers and wheel cylinders. Then shut every bleeder screw when fluid begins to drip. Fill the grasp cylinder reservoir yet another time earlier than persevering with.
Join one finish of the bleeder hose to the bleeder screw and insert the other finish right into a glass container partially full of brake fluid. Be sure that the tip of the bleeder hose is submerged in fluid.
Open the bleeder, after which have an assistant depress the brake pedal. As soon as the foot pedal is depressed, shut the bleeder. Repeat bleeding till the stream of fluid is obvious and freed from bubbles. Then transfer on to the subsequent wheel.
When do I would like a brake system flush?
For automobile upkeep, it’s endorsed to get a brake fluid flusheach two years or 30,000 miles, relying in your driving and braking patterns. This can stop a extra in depth and dear brake system restore, resembling whole brake failure.
Nevertheless, additionally, you will have to flush the brake system when sure signs seem, resembling:
1. Brake pedal feels spongy or smooth

And in case your automobile is low on brake fluid (which might translate to poor braking efficiency), it should routinely activate ABS to permit protected braking.
5. Unusual noises or smells throughout braking
For those who hear unusual sounds when braking, it may very well be as a result of a low brake fluid stage or a distinct downside with the brake system. Widespread unusual sounds embrace scraping or grinding noises.
Burning odors after braking may also point out that the brake fluid has been burned. In such a case, you want a brake flush as a result of driving with burnt brake fluid can result in different main brake issues, together with whole brake failure.
6. Brake fluid leak
You most likely want a right away brake fluid flush should you detect a brake fluid leak.
A brake fluid leak hampers braking effectivity because the power transmitted by way of the brake line is decreased.
To test the brake fluid stage, check out the brake fluid reservoir situated within the engine compartment. For those who can’t discover the brake fluid reservoir, seek the advice of your proprietor’s handbook for assist and different associated info.

- Clear particles left within the brake system
- Examine if the brake caliper, brake pad, brake rotor, brake pedal, or every other brake element must be changed.
- Exchange your brake fluid with new, high-quality fluid (clear fluid)
- Take away air trapped in every brake line with a bleeder
- Lastly, do a correct brake inspection to test if the brake system is working correctly.
3. Why is it essential to rinse the brake fluid?
Your braking system is necessary to your security. So if it isn’t in the perfect situation, you possibly can compromise a number of functioning automotive or brake elements.
Many of those automotive elements are linked collectively by brake strains and hoses that use brake fluid to transmit and amplify forces. That’s the reason it’s essential to preserve the fluid clear in order to not hinder the operation of any brake element.
A brake fluid flush service can be crucial to stop moisture buildup. It might probably result in corrosion of metallic brake elements resembling brake calipers, brake rotors, grasp cylinder, and so forth., compromising the complete brake system.
A easy brake fluid change ought to stop this corrosion of brake elements.
4. Why does brake fluid put on out?
Brake fluid, a hydraulic fluid, is chemically hygroscopic, which means it readily absorbs moisture.
That is dangerous information to your brake system elements, because the grasp cylinder, brake strains, metering valves, ABS, and calipers are all made from aluminum or metal, metals that corrode as a result of moisture.
Subsequently, anytime the brake system is uncovered to air (normally from the grasp cylinder reservoir), the brake fluid will soak up moisture. Ultimately, the contemporary, wholesome fluid turns rusty brown or black as a result of corrosion inside the brake system.
As fluid moisture will increase, the boiling level of brake fluid decreases, additional lowering the effectivity of dangerous brake fluid.
Use: Unhealthy brake fluid is a typical motive why the brake caliper and wheel cylinder begin to seize.
5. What does brake fluid do?
As you step on the brake pedal, a plunger pushes in opposition to the grasp cylinder, transmitting fluid by way of the hoses linked to the brakes.
When you have a disc brake, the fluid goes right into a brake caliper. The brake caliper then presses on a piston, squeezing the brake pad in opposition to the brake disc, forcing the wheel of your automobile to gradual or cease.
When you have drum brakes, fluid is compelled into the wheel cylinder, pushing the car’s brake footwear in opposition to the drum to gradual or cease the wheel.
In each instances, brake fluid is integral to establishing efficient communication between the brake pedal and the automobile’s brakes.
