Many people are beginning to have access to simple 3D printing allowing consumers to produce their own simple tools and fixtures.
File type .3MF
In the factory we’ve produced a few of these for our own staff and mechanics so we thought we'd open them up to you the consumers.
The tools range from simple travel pad spacers through to more complex bleeding fixtures and aids.
Each suitable for single head printing unless other specified
Recommended material PETG
Print fill >70%
THIN PAD SPACER
Prevents the pads to come in contact with each other accidently when the wheel is removed.
Simply clip the spacer onto the pad pin clip, pull down to remove
Prevents the caliper pistons to come out of the bore accidently when the pads are removed.
Simply install the spacer instead of the pads and secure with the pad pin
Pistons needs all to be pushed into their bores.
Although this tool could be use for bleeding the brake, depending on the material used and print fill percentage the lever could still feel spongier than it is.
E4 and RX4+ use the same tool
PISTON SERVICE TOOL
On 4 pistons calipers; allows a single piston to come out at the time to facilitate cleaning and lubrification.
The brake must be fully bled. Remove the pads, present the step in front of the piston you want to come out, install the tool instead of the pads and secure with the pad pin. Pump out on the master cylinder until the piston comes in contact with the tool.
PISTON SEAL SERVICE TOOL
Before caliper seal replacement, allows the inboard piston(s) to come out so they are easy to remove.
The brake must be fully bled. Remove the pads, install the U shape tool over the front ‘half’ of the caliper body, making sure the thinner leg of the U shape tool is in the pad location.
Pump the on the master cylinder until the inner piston(s) come in contact with the tool. Remove the tool and gently remove the pistons. The outer piston(s) will be removed once bore caps are unscrewed. The caliper will be now ready for seal replacement.
