Brake Pads, Removing And Installing, Brake 1LA/1LJ/1ZB/1ZT: Installing

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.

If old brake pads are being replaced with new ones, then it is necessary to check the brake rotor for wear. Pay attention to the brake rotor wear limit while doing this.

-- Check brake rotor, refer to FRONT BRAKES .

Tightening specifications, refer to OVERVIEW - FRONT BRAKES, 1LA, 1LJ, 1ZB AND 1ZT .

NOTE:

Always replace brake pads on the same axle at the same time.

Install on one axle on brake pads from the same manufacturer and with the same quality.

Install complete repair kit .

Use only mineral spirits or commercially available brake cleaner to clean the brake caliper.

-- Clean the brake caliper.

CAUTION:

Danger of contamination and paint damage from escaping brake fluid.

If the brake pads are worn out and brake fluid is filled, the brake fluid may overflow if the pistons in the brake cylinder are pressed back.
Check the brake fluid level before pressing back the pistons. If there is brake fluid up to the "MAX" mark, some brake fluid will need to be extracted.
Use the Brake Charger/Bleeder Unit VAS5234 to extract brake fluid from brake fluid reservoir.

-- Use the Piston Resetting Tool T10145 to press the brake piston completely into the brake caliper.

The brake pad has a mount -10- on the backing plate that must sit firmly in the brake caliper hole.

WARNING:

Both brake pads must sit under the retaining pins in the brake caliper. The brake caliper has two retaining pins at both left and right that must not be loosened.

-- Carefully slide the brake caliper with brake pads over the brake rotor.

-- Tighten the brake caliper on the brake carrier with both guide pins -4-.

-- Position the retaining spring -8- on the outer brake pad.

-- Press the retaining spring -8- in the center and insert the center tab of the retaining spring in the hole -arrow- on the brake caliper.

The retaining spring tab must sit correctly in the hole in the brake caliper or it can spring out and the brake pad will not be held in place.

NOTE:

The spring is tensioned, keep hands protected.

When removing the spring, make sure it does not scratch the brake caliper or damage the paint.

-- Insert the left front brake pad wear indicator connector in the bracket.

-- Insert the electric wire in the bracket -2- and lock it to the right -B-.
