Rear brake pads and rotors

[maryem]

It seems that my rear brake pads and discs need replacement. The repair handbook instructs to 'loosen the eyebolt and thereafter remove the brake hose' for either task (referring to the 'banjo' bolt for the hydraulic line). States, 'after installation, bleed the braking system.' On the older Picanto, changing brake pads was a straightforward task; however, for the newer model, it is suggested that one must detach the hydraulic line and thereafter bleed the brakes.

Has anybody changed the rear brake pads and/or discs without detaching the hydraulic hose?

It is advisable to bleed the brakes anyway.Seize the opportunity to remove some of the old brake fluid as well.
To retract the piston, let the old brake fluid to escape via the bleed screw.

In several vehicles, it is often feasible to shift the caliper away from the disc while it stays connected to the hydraulic supply. I have performed this procedure on many non-KIA vehicles, all of which instruct to disconnect and remove the caliper, and all were executed without detaching the hydraulic line.I am uncertain whether this is relevant to your specific vehicle; you will quickly discover the answer when you start the task.

The suggested way is likely more straightforward than laboriously working on your knees, especially if retracting the piston poses a challenge.

The accessibility to your vehicle is unclear to me, however bleeding the brakes is quite simple if access is adequate, and it is a favorable time to replace all the fluid anyway.

Air ingress into the system may be mitigated by using brake hose clamps positioned at the terminus of the hose on the wheel under maintenance. Typically, after eliminated, just a little amount of air remains to be exhaled. I own a pair of clamps that I have had for about fifty years; they are sometimes a valuable instrument.

For your information, the rear pads may be replaced without detaching the brake lines. Detach the brake cable bracket to provide further maneuverability. Rotate the pistons in a clockwise direction to retract them.

It is unreasonable to need the removal of the brake line to change the pads. I doubt Kia would have designed the servicing procedure in that manner; it likely indicates an error in the handbook or the directions for caliper removal.

I have never interfered with the hydraulics when replacing pads and discs. The disc holding screws on our 2013 model were seized, necessitating the use of an impact driver.

The service manual states that the brake line must be removed to replace the rear pads; however, as dm575 indicates, this is not necessary in practice. I agree with Kemal Zarr's reference to the need of an impact driver.
