Whereas this process could appear daunting, it’s a comparatively easy course of that may be completed with the best instruments and somewhat little bit of know-how. On this complete information, we’ll delve into the step-by-step directions on the way to take away a brake caliper safely and successfully.
Earlier than embarking on this process, it’s crucial to make sure you have gathered the mandatory instruments and supplies. You have to a socket wrench or spanner, a torque wrench, penetrating oil, brake cleaner, and new brake pads if required. Moreover, it’s advisable to have a brake fluid bleeding package readily available to take away any air from the brake traces after the caliper has been eliminated. Upon getting assembled these necessities, you’ll be able to proceed to the elimination course of. First, find the brake caliper on the wheel you want to work on. It’s usually a big, steel housing that encloses the brake pads and pistons. Earlier than disconnecting any elements, use penetrating oil to loosen the bolts that safe the caliper to the brake rotor.
As soon as the bolts have been loosened, you’ll be able to fastidiously take away the caliper from the rotor. Be conscious to not pull on the brake hose, as this will injury it. After the caliper has been indifferent, it is very important clear the surfaces the place it was mounted. Use brake cleaner to take away any dust or particles that will have collected over time. This can guarantee a correct seal when the caliper is reinstalled. If you’re changing the brake pads, now could be the time to take action. Align the brand new pads appropriately and insert them into the caliper. Lastly, reattach the caliper to the rotor and tighten the bolts to the desired torque utilizing a torque wrench.

- Take away the bolt as soon as it’s unfastened.
- Repeat steps 2-4 for the remaining mounting bolts.
| Tip |
|---|
| If the mounting bolts are rusted or seized, it’s possible you’ll want to make use of a penetrating oil or warmth to loosen them. |
Sliding Away the Caliper
With a delicate pull, use a rocking movement to fastidiously slide the caliper meeting away from the rotor; you’ll need sufficient room to entry the mounting factors.
For a floating caliper, a particular device referred to as a brake caliper spreader could also be required to unfold the caliper pistons again and create clearance.
If the caliper is especially caught, a penetrating lubricant will be judiciously utilized to the slide pins and caliper bracket to assist motion.
In older autos, the slide pins could also be closely rusted or seized inside the caliper bracket; these could must be changed.
Warning: Don’t pull the caliper away from the rotor; the brake hose wants to remain linked to keep away from injury.
Desk of Caliper Sorts and Removing Techniques
| Caliper Sort | Removing Technique |
|—|—|
| Floating Caliper | Use a caliper spreader or gently rock the caliper backwards and forwards whereas pulling |
| Mounted Caliper | Take away the caliper mounting bolts instantly |
Cleansing the Caliper Bracket
To completely clear the caliper bracket, observe these steps:
1. Take away any remaining {hardware}: Make sure you take away any bolts, pins, or different elements nonetheless hooked up to the caliper bracket.
2. Use a wire brush to take away rust: Make use of a stiff wire brush to clean away seen rust and corrosion from the bracket’s floor. Deal with areas the place rust accumulation is obvious.
3. Apply brake cleaner: Spray the bracket generously with brake cleaner to take away grease, grime, and brake fluid residue. Enable the cleaner to dwell for a couple of minutes earlier than wiping it off with a clear fabric.
4. Clear the piston bore: If the caliper has a sliding piston, clear the bore utilizing a piston bore brush. This specialised device helps take away any particles or corrosion that will have an effect on the piston’s motion.
5. Lubricate sliding surfaces: Apply a skinny layer of caliper grease to the bracket’s sliding pins or surfaces the place the caliper contacts the bracket. This lubrication ensures easy operation and prevents put on and tear.
6. Examine for injury: Study the caliper bracket for any indicators of cracking, bending, or different injury. If any injury is discovered, the bracket could must be changed.
7. Reassemble the caliper: As soon as the caliper bracket is clear and inspected, reassemble the caliper by following the reverse order of disassembly. Guarantee all bolts, pins, and elements are correctly tightened and secured.

Bleeding the Brake System
As soon as the caliper has been changed, it is very important bleed the brake system to take away any air that will have entered the traces. This course of will be completed by two individuals, or through the use of a one-person bleeding package.
Two-person bleeding:
- Have one individual pump the brake pedal a number of instances, then maintain it down.
- Have the opposite individual open the bleeder screw on the caliper, positioned on the high of the caliper.
- Enable the fluid to circulation out till it is freed from bubbles.
- Shut the bleeder screw and have the individual launch the brake pedal.
- Repeat steps 1-4 till the fluid is freed from bubbles and the brake pedal feels agency.
One-person bleeding:
- Connect the one-person bleeding package to the bleeder screw.
- Pump the brake pedal a number of instances, then maintain it down.
- Open the valve on the bleeding package and permit the fluid to circulation out till it is freed from bubbles.
- Shut the valve on the bleeding package and launch the brake pedal.
- Repeat steps 2-4 till the fluid is freed from bubbles and the brake pedal feels agency.
**Ideas for bleeding the brake system:**
- Use clear brake fluid.
- Bleed the brakes within the following order: proper rear, left rear, proper entrance, left entrance.
- Don’t over-tighten the bleeder screws.
- If you’re having bother bleeding the brakes, there could also be a leak within the system. Examine the brake traces and connections for any injury.
| Brake Fluid Sort | DOT Quantity | Boiling Level (°F) |
|---|---|---|
| DOT 3 | 3 | 401 |
| DOT 4 | 4 | 446 |
| DOT 5 | 5 | 500 |
Observe: DOT 5 brake fluid is just not suitable with DOT 3 or DOT 4 brake fluid.
