You can also use Shimano’s “Shimano Premium Grease” or similar products.

You can also use lithium or urea grease with NLGI grade #2 as a substitute.

The EQUAL mechanical disc brake caliper is compatible with short-pull brake levers (※) that actuate the brake via cable, just like rim brakes.Hydraulic disc brake levers are not compatible.

※ Short-pull levers may also be referred to as:
　・Road levers
　・Canti brake levers
　・Caliper brake levers
　・Mini V-brake levers(standard V-brake levers are not compatible))

Shimano, Campagnolo, SRAM, and other manufacturers have different lever ratios due to differences in design philosophy. However, our brake caliper is designed to target the median value across these manufacturers, making it compatible with any brand.
We have confirmed that it works without issue with both new and old brake levers from Shimano, Campagnolo, SRAM, and others.

Regarding the incompatibility of V-brake

When an EQUAL mechanical disc brake caliper is used with a lever designed for V-brakes (i.e., with a V-brake lever ratio), braking performance will be weaker compared to using a lever designed for canti brakes.
As this combination does not allow the caliper to perform as designed, V-brake levers are not supported.

Replacement parts are available.
Please contact the store where you made your purchase.

We recommend using the standard EQUAL brake pads.

If you choose to use third-party products, the system is compatible with Shimano ROAD-type pads such as K04 (metal), K03 (resin), and K05S-RX (successor to K03), as of March 2022.

When using third-party pads, please make sure to use the dedicated mounting bolts for the EQUAL disc brake caliper.

Please note that Shimano pads with cooling fins are not compatible.

If you operate the swing arm several times before installing the disc brake caliper on the bicycle, the piston may fail to return.
This occurs when the swing arm is rotated all the way into the “danger zone,” causing misalignment between the piston and the shaft.

If the piston does not return, press the swing arm fixing bolt (please refer to the dealer manual for details), and the piston and shaft will realign properly.

Please note that this issue will not occur once the caliper is installed and in regular use on a bicycle.

If you wish to use a 160mm rotor on the rear side, you will need to use a third-party adapter.

TRP adapters can be used as-is without any modification.
In the case of SHIMANO adapters, the mounting bolts are of a special design, and the pin section may interfere with the caliper. In such cases, you will need to modify the bolt by cutting the interfering part.

Please follow the adapter’s installation instructions to ensure proper mounting.

Brake pad clearance should be adjusted using the pad adjustment bolt.
While adjusting with the Brake-leverage adjustment bolt will change the position of the outer pad, it will also affect the brake feel.
If adjusted significantly, it may enter the “danger zone,” which can be hazardous.

Only use the Brake-leverage adjustment bolt in emergency situations—such as when you’re away from home, without a hex wrench, and the pads are significantly worn—where not adjusting the lever stroke would pose a safety risk.

Even in such cases, if squeezing the brake lever causes it to enter the danger zone, stop riding immediately.
