AI Technical Summary
Dismantling the front wheel of a power bike requires dismantling the brake caliper first, which leads to issues such as the caliper hanging freely, potentially damaging surrounding components, varying hole spacing in fork fastening holes, risk of thread damage, difficulty in caliper installation, and vibrations causing the caliper to swing uncontrollably.
A brake saddle holder with integrated stops and guide pins, made of plastic via FDM 3D printing, securely holds the brake caliper in place using guide pins as pivot points, compatible with various brake systems, and prevents damage to bike components.
Ensures safe and easy handling during wheel disassembly, compatible with different models, and prevents damage to brake calipers and fork threads, maintaining the caliper's position even with vibrations.

Abstract
Description
[0001] Technical area: Servicing the front wheel of a motorcycle. Problem: In order to remove the front wheel of a motorcycle, the brake caliper must first be removed. After this step, the brake caliper hangs freely in the air or on the brake line. This causes several problems. Firstly, the brake line must not be subjected to tensile stress by the weight of the brake caliper, and secondly, the hanging brake caliper can damage the surfaces of the surrounding components. Examples include the following components: the rim, fork tubes, and the motorcycle fairing.
[0002] In my opinion, known tools for this problem are not satisfactory because they: Point 1: They are made of metal, which can damage the brake caliper itself or the fork leg. Point 2: There is no universal solution for the different hole spacings of the mounting holes on the fork foot, since the holder is inserted into both threaded holes of the fork foot and this results in a fixed dimension that can vary from model to model. Point 3: The guide pins, which are inserted into the threads of the fork legs to secure the bracket, are also made of metal. This poses a risk of damaging the threads in the fork leg. Repairing the threads in the fork leg or replacing the fork legs after such damage would be very costly. Point 4: Pushing the brake calipers onto the holder requires considerable force, as the holder grips between the brake pads. (The calipers are then clamped only by the pressure of the brake pads against the holder.) This process can quickly cause damage to the brake pads. Point 5: When removing / installing the front wheel, the motorcycle experiences movement / vibrations. This movement / vibration is sometimes sufficient to prevent the brake caliper from being held in place, causing it to swing uncontrollably against the motorcycle, hanging from the brake line. My component: Brake caliper bracket for radially bolted brake calipers on motorcycles from SLR.moto. Construction:
[0003] There is a base body with an integrated stop. Two guide pins (A and B) are inserted into an octagonal slot on this base body and secured with two M4 cylinder head screws. How it works:
[0004] After removing the brake caliper, guide pin A is inserted into the lower mounting hole of the caliper. Then, guide pin B is inserted into the lower threaded hole of the fork leg. At this point, the guide pins also act as a pivot point. The brake caliper is then slowly lowered, locking itself against the stop by gravity. The brake caliper now automatically locates its position between the locking studs, thus preventing it from slipping.
[0005] The complete brake caliper bracket is manufactured in Germany using FDM 3D printing and is made of plastic, so the bracket cannot damage the brake caliper or the thread in the fork base. The guide pins extend deep into the motorcycle components, which, in conjunction with the locking nubs at the stop, ensures a secure fit. Multiple tests on various motorcycles have shown that the brake caliper stays securely in position even when the handlebars or fork are subjected to strong shaking. The design of the bracket eliminates the need to pay attention to the hole spacing of the brake caliper, as it only engages one of the two holes in the fork base and the brake caliper. The dimensions have been selected to accommodate all common brake calipers. Furthermore, the guide pins can be replaced if necessary, so that in the event of a defect, there is no need to buy a new entire bracket.The holder impresses with its simple and safe handling. Advantages summarized: - No dependence on the hole spacing of the mounting holes - Compatible with all common braking systems - Easy handling - Secure hold during all work on the motorcycle - No damage to the individual components possible - The holder can be used for the left and right side Final sentence:
[0006] Since the invention described in detail in this letter and the resulting design solution are not yet subject to protection, I hereby apply for initial registration and legal protection as my exclusive intellectual property.

Claims
[1] The brake caliper holder is made of plastic and has 3 main components: guide pin (A), guide pin (B) and the stop (D) with locking knobs (E). [2] The holder is fixed to the brake calliper using the guide pin (A). [3] The holder is fixed to the fork foot using the guide pin (B). [4] Guide pins (A) and (B) also function as a rotation axis. [5] The brake calliper is interlocked against the stop (D) via the guide pins (rotation axes) (A) and (B) when lowered.
