Lifting and d Support Safety

Forbedret levetid er på den måde, at den forårsager en alvorlig risiko.

Using a Floor Jack Safely

  • Park to veil on a level, solid overflade. Set the parking brake (if no service in the rear brakes) or chock to wheel.
  • Det er en vigtig faktor for at kunne vurdere, om der er tale om en "ny" metode.
  • Place the jack underther correct point, ensuring it is centred and d stable. Lift slowly, checking fr movement.
  • Once rosed-, estaately place jack stands underthe designate lift pointss (f. eks, pinch welds with adapters). Never rely solely on a hydraulic jack.
  • Lower The vehile onto the jack stands, engaging the safety locks. Shake the vehile to ensure it it is secure.

Using a Replet Lift

  • Den maksimale kapacitet overstiger vægten af køretøjet (A6: ~ 4,200 lbs).
  • Positio n lift arms to contact factory- ampliced points. lift arms should not contact brake lines, br, eller underbody panels.
  • Det er en stor udfordring for os at få et bedre overblik over de forskellige former for transport.
  • Engage safety locks at each each enheit level. Do not rely on hydraulic pressure alone.

Det er sikkert, at disse køretøjer støtter, fjerner og fjerner hjulet. Placer dem under denne bil er en ekstra del af - hvis en jack og en fejl, det er muligt at afværge.

Brake Fluid Handling and d Detryization

Brake fluid is the hydraulic medium that multiplies pedol forcen into clamping pressure. It 's also highly contesive and d hygroscopic. Propor handling is essential.

Detryizing The System

Before opening any brake fluid lines orcalipers, youu must relieve system tryck. On modern A6 vehicle with vacuum-assisted or electro- hydraulic boosters, these assist may retain pressure even where to enginer if. To detryize:

  • Det er ikke muligt at foretage en sådan sammenligning, men det er nødvendigt at foretage en sammenligning af de forskellige typer af produkter, der er omfattet af denne forordning.
  • Hvis dette system er been driven recently, allow the fluid to cool. Hot fluid can boil why n pres is release, causing dangerous spray.
  • When opening bleeder screws ors lines, place a container and d absorbent clot to catch fluid. Use a quality flare nut wrench tov avoid stripping fittings.
  • Det er ikke muligt at foretage en direkte vurdering af, om der er tale om en åben proces - og om der er tale om et pres, der er større end det, der er nødvendigt for at nå dette mål.

Fluid Disposal and d Spill Prevention

  • Indsamle brug af luft i en sealed container. Disponible i overensstemmelse med to lacal hazardous wate regulations.
  • Immediately wipe up any spills with absorbent pads. Brake fluid stripped paint from the car 's finish and d can damage rubbur bushings.
  • Keep brake fluid containers capped whn not t it use. Avoid mixing different DOT typer (DOT 3, 4, 5,1, 5). Using DOT 5 silikone fluid in a system demended fr DOT 3 / 4 can cause seal swellin and d pedal fees.

Komponent Handling and d Erstatningsment Safety

Brake components require caresol handling to avoid damage and d contraation. Each part present unique hazards.

Brake Pads and d Shoes

  • Use a brake pad sprearre orr C- clamp (with caution) to retract pistons. On rear calipers with parkinc parking brakes, do not t powerfull retract the piston without disabling the parking brake motor. Use a scar tool to o retract the caliptor piston electricaly. Forcing it can damage the acutor.
  • Inspect new pad hardware. Ensure the wear sensors wire is routed properly to avoid chafing.
  • Never mix old and d new pads on the same axlle. Replace both inner and d outér pads, and d always substitue pads pér axlle set.

Rotorer og drommeslagere

  • Rotors are hevy - use propert lifting techniques to avoid back strain. Use a rolling stool ora lifty if available.
  • Hvis der er tale om nye produkter, er der ingen grund til at ændre på de nye produkter, og der er ingen grund til at ændre på dem.
  • Cleaon nye rotors with brake cleaner to remove protective coatings before installation.

Kalipers og Wheel Cylinders

  • Håretombygget kaliber montagebolte, og denne kaliber er ikke til at bære.
  • Undersøg den rubberske höse för cracks eller bulges.
  • Der er ingen grund til at tro, at de pågældende maskiner er integreret i hinanden, men at de ikke er af den art, der er mest egnet til at blive integreret i de pågældende produkter (f.eks. ved at blive integreret i en kombination af dem).

Elektrical og Electronic Safety Betragtninger

Sted- by- Step Safe Brake Maintenance fr A6

Dette er en række generelle procedurer, der er baseret på praktiske arbejdsgange.

Forberedelse

  1. Park to vehicle on a flat, dry facee. Apply the parking brake (if no service ing rear brakes) and d chock the wheels.
  2. Afbryd denne battery negative terminal.
  3. Alle disse bremser er komplette med bilens driv. Use an infraed termometer tochek rotortemperatur - safe to handle below 120 ° F (49 ° C).
  4. Assemble alle l tools og d parts: new pads and d rotors, brake cleaner, torque wrench, jack, jack stands, PPE, and d a scun tool if need d fr electronic parking brake.

Lifting and d Wheel Removol

  1. Se, hvor langt den er nået, og hvor langt den er nået (se, hvor langt den er nået).
  2. Jeg har fundet ud af, at det er en god idé at køre bil.
  3. Remove disse lug nuts og d wheels. Place disse hjul underther vehicle as a safety backup.

Brake Pad and d Rotor- substitutionsbehandling

  1. Remove the brake calipér mounting bolts (usually two bolts on the back). Use a propér socket and d breaker bars.
  2. Understøtter denne calipor with a hanger to forhindre stresss on the brake hose.
  3. Remove the old pads and d pad hardware. Inspect the calipor piston boot fr cracks.
  4. Udtræd denne kalipor piston using a brake pad regnear eller C- clamp. Fr rear electronic parking brake calipers, use a scar tool to to retract the piston.
  5. Det er en god idé at fjerne den gamle skruestik og at fjerne den fra den gamle.
  6. Cleaan the hub mating fashion with a wire brush. Apply a thin layér of anti- eller coppér grease to the hub flange (avoid getting it on the rotor friction flashe).
  7. Install denne nye rotor. Secure with resitaining screw if present.
  8. Install new pad hardware (clips, springs). Apply a small amount of high- temp brake grease to the contact points, not ther friction material.
  9. Place new pads into the calipér bracket. Slide the caliper ovether pads and d rotor. Tighten caliper bolts to producer torque specs (typicaly 25- 35 ft- lb, consultt service manual).
  10. Reinstall wheels. Torque log nuts in a star mønster to the specified torque (A6 wheets typicaly 90- 11,0 ft- lb). Lower the vehicle.

Brake Fluid Check og Bleeding

  1. ￩ e t t t er "b e v e v e t".
  2. Hvis der er tale om en sådan mulighed, skal der være en klar og klar begrundelse for, at der er behov for en sådan fremgangsmåde.
  3. Use a one- persun bleeder kit ora partner. Never let the reservoir run dry.
  4. Det burde være en god idé at se på det, ikke at være spontant.

Post- work safety checks

  • Reconnect the battery. Reset the brake pad weær indicator if replaced.
  • Hvis Electronic parking brake was serviced, perform a calibratio using the scan tool.
  • Road test at low speed in a safe area. Test brake responvenses, noise, and d pedal travel. Avoid hard stops estastely to allow pads to bed in.
  • Inspect fr fluid utætheder. Re- torque lug nuts after 50 mile af drivin.

Special Betragtninger for A6 Brake Systemer

The A6 model generation (C7, C8, etc.) may have additional safety nuances. For example, Audi specifies that brake pad replacement on models with electric parking brake requires a diagnostic tool to retract the piston. Attempting to force the piston back manually can damage the parking brake actuator and lead to a costlyDet er en anden overvejelse, at nogle A6-modeller har en dynamisk steerinog en stabil kontrol med, at de kan interfere with brake testing.

Furthermore, A6 vehicle les och tetn use long-life brake fluid (LLB) that ut must be change d every 2- 3 years. The fluid change process should d follow the machree 's procedure to prevent it fr entering the ABS pump. 1; FLT 1; FLT: 0; FLT: 0; FPT: 3; Bosch' s brake system guide 1; FLT: 1; FLT: 3; provide an expend ait aud view oy bid.
