Brake caliper, wear indication device, and vehicle brake

A wear indication device (200) for a brake caliper (10) comprising:

• a fixation device (210) configured to engage a brake pad carrier (140) that has a carrier plane (142) for carrying a friction lining (120) and a rear plane (144) opposite the carrier plane (142), and
• a signal wire (220) having a looped portion (222),
• wherein the fixation device (210) has a front part (214) for engaging the carrier plane (142), a back part (216) engaging the rear plane (144), and a bridge (217) connecting the front part (214) and the back part (216),
• wherein the looped portion (222) of the signal wire (220) is at least partly arranged externally on the front part (214) of the wear indication device (200) configured to project toward a contact surface (121) of,
• wherein a hook (226) extends from the back part (216) of the fixation device (210), said hook (226) engaging with said looped portion (222);
• wherein the hook (226) includes a first portion (228) extending from said back part (216), and wherein said first portion (228) is aligned substantially in parallel to said bridge (217), wherein the hook (226) includes a second portion (230) extending from the first portion (228), and wherein said second portion (230) is aligned substantially in parallel to the back part (216) and extends towards said bridge (217).

A vehicle brake (1) comprising:

• a brake disc, and
• a brake caliper (10) forming an accommodation space for the brake disc, the brake caliper comprising:
• a brake pad (100) having a friction lining (120) and a brake pad carrier (140) carrying the friction lining (120) proximate to the brake disc, wherein the brake pad carrier (140) has a carrier plane (142) for carrying the friction lining (120) and a rear plane (144) opposite the carrier plane (142);
• wherein the friction lining (120) has a contact surface (121) facing away from the brake pad carrier (140) that bears against the brake disc during braking, and
• a wear indication device (200) having a fixation device (210) and a signal wire (220) including a looped portion (222),
• wherein the fixation device (210) has a front part (214) engaging the carrier plane (142), a back part (216) engaging the rear plane (144), and a bridge (217) connecting the front part (214) and the back part (216),
• wherein the looped portion (222) of the signal wire (220) is at least partly arranged externally on the front part (214) of the wear indication device (200) and projects toward the contact surface (121),
• wherein a hook (226) extends from the back part (216) of the fixation device (210), said hook (226) engaging with said looped portion (222);
• wherein the fixation device (210) includes a bar (212) extending from the front part (214) parallel to the carrier plane (142), wherein the bar (212) engages the signal wire (220) proximate to the carrier plane (142),
• wherein the fixation device (210) has a recess (218) in the back part (216) configured to guide the signal wire (220), wherein the recess (218) of the fixation device (210) at least partly overlaps a recess (146) defining a through-hole through the brake pad carrier (140),
• wherein the looped portion (222) of the signal wire (220) at least partially loops around the bar (212) and extends through the recess (146) of the brake pad carrier (140) device (210), and a back end portion (224) of the signal wire (220) extends through the recess (218) of the fixation device (210) and at least partially loops around the hook (226).
