About ISR Calipers

Materials

• The calipers are machined from aluminium alloy and have a clear, hard anodised finish for protection.
• The pistons are also manufactured from aluminium alloy and are coated with TUFRAM. This specialised aluminium coating combines the hardness of aluminum-oxide ceramic with the properties of selected proprietary polymers, providing aluminum parts with new levels of hardness, wear and corrosion resistance, and permanent lubricity.
• Any caliper carrier supplied is made from the same material as the calipers.

Fitting and maintenance

• All calipers use a standard banjo bolt fitment for brakes lines of M10x1.25mm.
• The brake pads are held in position using a pin and 'R' clip system. This simple yet effective method makes it easy to change pads quickly.
• The majority of calipers come supplied with large, hard anodised bleed bolts with a separate, removable bleed nipple.
• Virtually all parts of the caliper are replaceable, making them a cost effective solution.
• In some cases, the calipers are direct replacements for standard discs and forks, but if not, mounting brackets can be provided to suit both standard and oversized disc sizes.
• Detailed dimensional diagrams are available on request.

Master cylinder requirements...

If you are upgrading to bigger calipers, you need to ensure that your master cylinder can cope with the increased pad area to get the full braking improvement.

ISR Brakes Discs

Materials...

• The carrier is machined from aircraft specification aluminium billet. This makes it stronger and more rigid than carriers pressed from aluminium sheet. The design is optimised to give the best compromise of strength and weight.
• The carrier is anodised for protection.
• The buttons are again crafted from aluminium billet and anodised for protection. Although they look traditional from the outside, the inside reveals a different story, with a flat "drive" transmitting braking power efficiently through the whole disc. This design also prevents the disc from "rolling" against the buttons when the rotor heats up which helps to prolong the life of the whole disc.
• The rotor is cut from a solid steel alloy bar and not sheet metal. This increases strength and rigidity, making the rotor less susceptible to warping and cracking. The material the rotor is made from has the same friction properties as cast iron, helping you to stop quicker, but is slightly lighter and not as brittle. The coating applied to prevent corrosion wears off after a few miles.
• The rotors are drilled to make them lighter and also to help heat dissipate. They also provide an escape route for gas and brake dust which, if allowed to built up between the disc and pad, can reduce braking efficiency.

Fitting and maintenance...

• If the disc size is being changed from standard, it is highly likely that you will need to move the caliper to a new position by means of a caliper mounting bracket. We can supply these for ISR calipers and they are included in the kits and conversions that we supply.
• When it is time to replace the rotor, no special tools are required to dissasemble the disc. Using a simple screwdriver, all the buttons can be undone in 5 minutes.
• When reassembling the disc, no shimming is required to obtain the correct amount of float. This is built into the button design.

ISR Master Cylinders & Clutch Levers

• The master cylinders and clutches are machined from aluminium alloy and have a clear, hard anodised finish for protection.

Fitting and maintenance

• All master cylinders and hydraulic clutches use a standard banjo bolt fitment for brakes lines of M10x1.25mm
• Banjo bolt fitment on all front master cylinders and hydraulic clutches is parallel to the handlebar.
• The wire clutches run standard Japanese/European cables. A special lever is available for Harleys.
• Master cylinders designed for standard sized handlebars are also suitable for "fat" handlebars which have standard sized ends.
• It is recommended that brake fluid is replaced at least yearly to avoid moisture causing any damage to the seals, etc.

Adjustment details

• All the master cylinders and hydraulic clutches come with adjustable ratio. The range of adjustment is 5:1 to 3.8:1. In layman's terms this means that when set to the minimum (3.8:1) you have to move the lever further to get the same braking effect but there is a lot more sensitivity in the feel of the brakes.
• The reach adjustment is carried out by hexagonal adjuster on the lever; moving the adjuster clockwise lowers the ratio and anticlockwise increases it. There are no positve stops allowing any ratio between the extremes to be selected, giving maximum adjustment capability.
• The adjustable levers have a total adjustable range of 28mm. Adjustment can be easily carried out while riding using the index finger, without the need to let go of the handlebar or throttle.
