Putting in brake strains is a important job that requires precision and a focus to element. If the brake strains usually are not put in appropriately, it may result in a lack of braking energy, which will be harmful and even deadly. That is why it is vital to comply with the right steps when putting in brake strains. On this article, we are going to give you a step-by-step information on the right way to set up brake strains. We will even give you some tips about the right way to keep away from frequent errors.
Earlier than you start, you will need to collect all the instruments and supplies that you’ll want. This features a brake line flaring software, a brake line bender, a brake fluid, and a wrench. Upon getting all the needed instruments and supplies, you may start the set up course of. Step one is to take away the previous brake strains. This may be performed by utilizing a wrench to loosen the brake line fittings. As soon as the previous brake strains have been eliminated, you may start to put in the brand new brake strains.
The subsequent step is to bend the brand new brake strains to suit your automobile. This may be performed utilizing a brake line bender. As soon as the brake strains have been bent to suit, you may start to put in the brand new brake line fittings. The brake line fittings must be tightened utilizing a torque wrench. As soon as the brake line fittings have been tightened, you may start to fill the brake system with brake fluid. As soon as the brake system has been full of brake fluid, you may start to bleed the brakes. Bleeding the brakes is vital to take away any air from the brake system. As soon as the brakes have been bled, you may start to check the brake system.

Here’s a desk of brake line routing ideas:
| Part | Routing Tip |
|---|---|
| Grasp cylinder | Route the brake strains away from the exhaust manifold and different warmth sources. |
| Brake calipers | Route the brake strains in order that they don’t seem to be kinked or broken. |
| Wheel cylinders | Route the brake strains in order that they don’t seem to be kinked or broken. |
Upon getting routed the brake strains, it’s worthwhile to bleed the brake system to take away any air from the strains.
Flaring and Bending the Brake Traces
Upon getting the brake strains reduce to size, you’ll need to flare the ends. Flaring is a strategy of increasing the tip of the brake line in order that it may be hooked up to a becoming. There are two major varieties of flares: single flares and double flares. Single flares are simpler to make, however double flares are safer.
Single Flaring
To make a single flare, you’ll need a flaring software and a flaring block. The flaring software is a handheld system that has a cone-shaped tip. The flaring block is a metallic block that has a gap within the middle. The opening is sized to suit the brake line.
Double Flaring
To make a double flare, you’ll need a flaring software and a flaring block. The flaring software is a handheld system that has a cone-shaped tip. The flaring block is a metallic block that has a gap within the middle. The opening is sized to suit the brake line.
Upon getting flared the ends of the brake strains, you’ll need to bend them to suit your automobile. You should utilize a brake line bending software to make exact bends. For those who would not have a brake line bending software, you need to use a pair of pliers to fastidiously bend the brake strains.
| Flaring Device | Flaring Block |
|---|---|
| $20-$50 | $10-$20 |
Upon getting bent the brake strains, you may set up them in your automobile. Be sure to tighten the fittings securely.
Connecting the Brake Traces to the Elements
6. Connecting the Brake Traces to the Calipers or Wheel Cylinders
Instruments and Supplies:
Steps:
| Flare Kind | Instruments Required | Course of |
|---|---|---|
| Single Flare | Flaring software, brake line wrench | Creates a flared finish on one facet of the brake line. |
| Double Flare | Double-flaring software, brake line wrench | Creates a barely flared finish on each side of the brake line. |
Bleeding the Brake System
As soon as the brand new brake strains are put in, it is essential to bleed the brake system to take away any air trapped inside the strains. Air could cause a spongy or lack of brake pedal really feel, which will be harmful when driving. The bleeding course of includes forcing the air out of the system utilizing hydraulic strain and changing it with brake fluid.
Steps:
1.
Collect instruments and security gear:
You will want a brake bleeding equipment, which features a clear plastic hose, a wrench, and a container for the previous brake fluid. Put on security glasses and gloves to guard your self from brake fluid.
2.
Begin with the farthest wheel from the grasp cylinder:
That is sometimes the appropriate rear wheel. Connect the hose to the bleeder valve on the wheel caliper and submerge the opposite finish within the container.
3.
Have an assistant press the brake pedal slowly:
As they maintain the pedal down, you open the bleeder valve barely, permitting the brake fluid and air to flee into the hose.
4.
Shut the bleeder valve:
When you see a gentle stream of brake fluid with none air bubbles, shut the bleeder valve and have your assistant launch the brake pedal.
5.
Repeat steps for the remaining wheels:
Transfer to the left rear wheel, adopted by the appropriate entrance and at last the left entrance wheel. Guarantee to maintain the grasp cylinder topped up with brake fluid throughout this course of.
6.
Verify brake fluid stage:
As soon as all wheels are bled, examine the brake fluid stage within the grasp cylinder. It must be on the “full” mark. If not, add extra fluid till it reaches the right stage.
7.
Pump the brake pedal:
With the engine off, pump the brake pedal repeatedly to construct up strain within the system. It will assist guarantee all air is eliminated and the brakes are totally useful.
Testing the Brake Traces
After finishing the brake line set up, the subsequent essential step is to completely check them to make sure their performance and security. Here is a complete information on the right way to check brake strains:
Supplies Required
| Merchandise | Goal |
|---|---|
| Brake pedal melancholy software | To simulate brake pedal melancholy with out driving |
| Brake fluid | To fill the brake system |
| Bleeder screw wrench | To open and shut bleeder screws |
| Clear hose | To attach bleeder screws to a catch container |
| Catch container | To gather brake fluid throughout bleeding |
Testing Process
1. Security First: Put on security glasses and gloves all through the method.
2. Fill the Brake System: Use the suitable brake fluid on your automobile and fill the grasp cylinder to the really helpful stage.
3. Join the Brake Pedal Despair Device: Connect the brake pedal melancholy software to the brake pedal and simulate brake pedal melancholy.
4. Open Bleeder Screws: Beginning with the wheel furthest from the grasp cylinder, open the bleeder screws one after the other.
5. Connect Clear Hose: Join a transparent hose to the bleeder screw and submerge the opposite finish in a catch container.
6. Bleed the Brakes: Use the brake pedal melancholy software to push brake fluid by the strains and out the bleeder screws. Tighten the screws as quickly because the fluid begins flowing.
7. Repeat for Remaining Wheels: Repeat the bleeding course of for every wheel, beginning with the furthest one and dealing in direction of the grasp cylinder.
8. Verify for Leaks: Examine the brake strains and connections completely for any leaks. Tighten any unfastened fittings as needed.
9. Ultimate Checks:
– Take a look at the brake pedal really feel by miserable it a number of occasions. It ought to really feel agency and responsive.
– Verify the brake fluid stage once more and prime up if wanted.
– Drive the automobile cautiously and check the brakes at low and reasonable speeds.
– Hear for any uncommon noises or vibrations whereas braking, which can point out an issue.
