 Ford F-150 5.4 V8 pidurite probleem
Mure järgmine:
Piduripedaal pehme ning vajub põhja.
Pidureid on korduvalt õhutatud ning õhku sees ei ole.
Peasilindril on mansetid 2x vahetatud aga ei ole abi olnud.
Piduripedaali vajutamisel liigub vaakumvõimendi veidi ning aegajalt on ka mingit susinat pedaali vajutamisel korra kuulda.
Kas võimendi ise õhtal? On äkki keegi sarnase probleemiga silmitsi seisnud?
Edit: auto aastast 2001.

Ford F-150 5.4 V8 pidurite probleem
Kuna sa auto aastat ei kirjuta siis leidsin selle ostukuulutusest ja loodan, et on õige. '01 kastikal on piduri peasilindri lõpus andur püsikiirushoidja jaoks, õhuta ka sealt kaudu muidu jääb sinna lõppu õhk sisse.

Ford F-150 5.4 V8 pidurite probleem
Kahjuks ei ole antud masinal peasilindri küljes ühtegi andurit.
Silindirl ainult kaks väljuvat toru ning peal õlipaak.

Ford F-150 5.4 V8 pidurite probleem
Panen siis veel ühe õpetuse ehk abiks.
MASTER CYLINDER
Master Cylinder Bleeding (Bench)
Support brake master cylinder body in a vise, and fill brake master cylinder reservoir with DOT 3 brake fluid. Install plugs in front and rear brake outlet ports. Bleed front brake system first. Loosen plug in front brake outlet port and depress primary piston slowly to force air out of master cylinder.
Tighten plug while piston is depressed or air will enter brake master cylinder. Repeat procedure until no air bubbles are present. Repeat bleeding procedure for rear brake outlet port with front brake outlet plugged. Tighten plugs and try to depress piston. Piston will not depress if all air is out of master cylinder.
Master Cylinder Bleeding (On Vehicle)
Using a tubing wrench, remove brake tubes from master cylinder. Install short brake tubes in master cylinder and position so they curve into master cylinder reservoir. Ensure ends of tubes are submerged in brake fluid.
Fill master cylinder reservoir with new DOT 3 brake fluid. Have an assistant pump brakes until clear, bubble-free fluid flows from both brake tubes. Remove short brake tubes, and reinstall brake tubes on master cylinder. Bleed each brake tube at master cylinder by having and assistant pump brake pedal 10 times and hold firm pressure on brake pedal.
Loosen rearmost brake tube fittings until a stream of brake fluid comes out. Have an assistant maintain pressure on brake pedal until brake tube fitting is tightened again. Repeat procedure until clear, bubble-free fluid comes out from around tube fitting. Refill master cylinder reservoir as necessary. Repeat this bleeding operation at front brake tube fittings.
SYSTEM BLEEDING
Conventional Manual Bleeding
Remove dust cap from right rear wheel bleeder fitting. Connect hose to bleeder fitting. Submerge other end of hose in container of clean brake fluid.
Loosen bleeder fitting while an assistant presses brake pedal through its full travel. Close bleeder fitting. Wait 5 seconds. Repeat procedure until air bubbles are no longer present at submerged end of hose.
Repeat procedure at left rear, right front and left front wheels. Refill reservoir after each wheel is bled. When complete, adjust fluid level.
Conventional Pressure Bleeding
Clean reservoir cap area. Connect pressure bleeder following manufacturer's instructions. Remove dust cap from right rear wheel bleeder fitting. Attach hose to bleeder fitting. Submerge other end of hose in container of clean brake fluid.
CAUTION: DO NOT exceed 50 psi (3.5 kg/cm2 ) during bleeding.
Open valve on bleeder tank to pressurize system. With brake pedal released, open bleeder fitting until air bubbles no longer emerge from submerged end of hose.
Repeat procedure at left rear, right front and left front wheels. When complete, close pressure bleeder tank valve, remove adapter and adjust fluid level.
Hydraulic Control Unit (HCU) Bleeding
Bleed brake system using conventional bleeding procedure. Connect New Generation Star (NGS) tester to Data Link Connector (DLC). Turn ignition on. Enter vehicle identification information. Choose DIAGNOSTIC DATA LINK from menu selection.
Next, choose ABS MODULE, FUNCTION TEST, and SERVICE BLEED FUNCTION. Follow scan tester instructions until SERVICE BLEED PROCEDURE COMPLETE message is displayed. Repeat conventional bleeding procedure. If brake pedal feels spongy, repeat complete procedure.
