Do you want to take care of the maintenance of your bike? Find out how to change your brake pads safely. In this article, you will learn how to assemble and disassemble your brake pads, how to know when to replace them, and how to choose your new brake pads.
Here’s all you need to remember!
How to change the brake pads of his bike?
Tips before starting disassembly
Before disassembly, make sure you have enough brake fluid available. This will allow you to redo the level when needed.
Take care to check the tightness of everything you are going to loosen. And when you move a piece, make sure it is methodically put back to its original location. Remember to check your technical review to get into the procedure of disassembly/reassembly of the brake pads.
Disassemble the brake pads
To disassemble your brake pads, here are the steps to follow:
- Replace the brake fluid reservoir: remove some of the brake fluid with a large syringe. Its level must be low so as not to overflow when pushing on the pistons. The jar must never be empty.
- Remove the brake caliper: as a rule, the caliper is fixed by two screws at the bottom of the fork (BTR or hexagon) or masked by covers. So, if your bike has double calipers, pull out one caliper after the other. Start by unlocking first by removing the bolts and then separating them from the disc.
- Remove the brake pads: two pins inside the caliper hold them. These supports are often screwed or carried using pins. To do this, first, unlock both axles before removing your brake pads.
- Clean the caliper pistons: Use a special brake cleaner to clean the cylinders to maintain their tightness thoroughly.
- Push the pistons: to do this, and you can help a screwdriver to leverage. You will then observe that the level of liquid is raised in the jar of brake fluid.
Fit the new brake pads
The pads are housed in the groove at the bottom of the stirrup, with the packing placed outwards. Make sure the entire device is correctly assembled before tightening the axle and replacing the pins and the caliper.
To reassemble the stirrup on the disc, it is necessary to keep the pads apart (use a finger) and slide all on the drive. Once the device is in place, you can now reattach the caliper.
Remember, the pads and the disc should not be stained with grease! And think of putting a few drops of thread lock on the threads of the bolts before tightening.
Once the various elements are put back in place, you have to check.
- Begin by refilling the brake fluid level in the jar and pull the brake lever several times;
- Make sure the circuit is working well again;
- Finally, a small break in the brake pads will be necessary to test the implementation of new pads.
Finally, know that it is not advisable to mount new pads on a worn disc. Also, be careful not to install your brake pads upside down. Such an error is dangerous for your safety and would also accelerate the wear of your brake equipment.
Know when it’s time to replace your brake pads
Once they are put to the test of time, these parts deteriorate rapidly. At each braking of the bike, the friction created will cause a loss of material.
Hence the need to replace them! Do not forget that it’s about your safety …
The thickness of the filling: a key indicator
Made of a lining and metal support, the brake pads play an essential role in maintaining the brake disc of your motorcycle. Their action makes it possible to press on the drive to create friction, which slows down its rotation. This contributes, at the same time, to slowing the wheel of the bike.
When wear is installed, you will visually see a loss in the pad lining and on the brake disc.
It is advisable to change the brake pads before they lose their trim completely. This prevents the metal bracket from coming into contact with the brake disc, which could cause scratches on the drive. That would force you to change the whole mechanism!
The thickness of the brake pad lining is to be monitored regularly. If it reaches 2 mm, then it’s time to replace them. A wear indicator is found on the vast majority of brake pads and is in the form of a small groove. If one of the wear indicators shows you that it is time to change a brake pad, change both.
Be aware that vibration or braking noise are also clues that should alert you.
Update on the frequency of change
There is no ideal frequency to replace its brake pads. Their wear is very variable according to several factors such as:
- the frequency of use of the motorcycle
- driving style
- The environment in which we drive (urban use, motorway, countryside …). Urban use, which regularly requires stops or slowdowns, will promote the wear of pads compared to regular driving on a conventional road or highway.
- The driving conditions …
It’s up to the rider to learn to recognize wear. Generally, it is felt by the reduced effectiveness of braking. If you need more time to stop, it is necessary to think about replacing the brake pads. Do not forget to check the condition of your brake pads after each course of about 5,000 km.
Choosing the right brake pads
For optimum safety, always select a model of pads that perfectly matches the quality of your discs and your use. That’s why you need to evaluate certain factors before choosing a model.
For example, if your motorcycle has a cast-iron disc, it would be prudent not to choose the sintered metal brake pads.
Also, check the composition of the filling and the thickness of the pads. Know that an organic lining is softer, so it deteriorates faster than metal.
In terms of efficiency, organic platelets are suitable for general road use. Those made of sintered metal can be chosen for journeys that require a lot of braking. On the other hand, racing pads have an efficiency threshold located around a temperature of between 150 and 200 ° C. They are suitable for heavy road use.
