Checking brake pad wear
1. Check the thickness of the front brake pads as described in Chapter 3.
2. On models with rear disc brakes, also check the rear brake pads as described in Chapter 10.
Checking for leaks and the condition of hydraulic lines
3. Support the car in a raised position, remove all wheels.
4. Check up, whether there are leaks and damages of tubes and hoses of brake system. Check for corrosion on the brake pipes.
5. Check the condition of the flexible hoses. Check that they are not twisted and do not touch the body or surrounding parts.
6. Check the condition and leaks from the master cylinder, booster block, pressure regulator, calipers, working brake cylinders and, where ABS is installed, the hydraulic modulator. Check that the mounting nuts and bolts are secure.
Checking wear on the rear brake shoes
7. On models with rear drum brakes, check lining thickness as described in Chapter 7.
Checking the brake fluid level
8. Check up, that level of a brake liquid in a transparent tank was between labels 'MIN' and 'MAX'. Note that a slight drop in level is acceptable as the brake pads wear. If the level drops rapidly in a short time, or if it reaches the 'MIN' mark, check for leaks in the hydraulic line.
9. After repairing or bleeding the system, top up to the 'MAX' level using the recommended fluid.
Brake Fluid Replacement
10. Remove the filler cap from the reservoir and aspirate the liquid with a syringe or pipette.
11. Attach a booster tube to each bleeder port as described in Chapter 17, and pump the brake pedal until all the fluid is out of the system. Tighten the bleeder plugs before continuing.
12. Fill the system with new brake fluid according to Chapter 17.
13. On manual transmission models, it is recommended to bleed the clutch hydraulic line at the same time, otherwise the new fluid will be contaminated with the old one.
