Question about Ford E-350 Super Duty

1 Answer

Brakes 2000 E450 Ford V10, replaced rear calipers due to their being siezed up. Bled brakes conventionally, but still no pedal while running. Will build up somewhat when not running, but while running goes to floor and have only front brakes. Can hear calipers in rear moving to indicate some function. No hissing noises to indicate booster problem. Cannot locate a RABS block. May be looking in wrong spot... This is an E450 Super Duty Motorhome chasis. HELP!

    I have bled over a quart of fluid through the system. Still spongy at best. Had good pedal prior to replacing calipers, so I don't suspect the master.... But I cannot seem to get the air out, if it is there.

    This still sounds like you have air in the system. I would bleed your brakes again and make sure that there is plenty of fluid in your master cylinder...

Check to see you haven't mounted the calipers on the wrong sides. bleeders should be on top not the bottom. RABS block is on the framerail near the drivers door

2001 Silverado 2500 HD Why Rear brakes don't work after I installed new hydro-boost power booster, master cylinder, calipers, and pads. I bled master cylinder before installing, and brakes beginn


Hello Patricia,

Have you checked the master brake cylinder reservoir for brake fluid loss?

I don't suspect the master cylinder as you have replaced it... but am more suspect of a leaking brake line or fitting which should have
been discovered when you had the system bled.

The only time I ever had a rear brake problem with a 2500 series Chevrolet was due to seized rear brake caliper guide pins...as your calipers are also new that is not your problem.

If your brake pedal feels spongy and travels to the floor board you have air in the system, a brake fluid leak or a failure in the power steering system, such as a broken hose, broken power steering pump drive belt, or failed pump, would result in a loss of pressure to both the hydro-boost and steering.

In this case, you will need to leak the for wheels, never leak only one or two wheels when adjusting the breaks. If the leaking continues you need to check the conduit for potential damages. If pedal stay soft after checking everything else, check the break fluid unit. The unit has a piston if I'm not wrong. The piston has some parts that are of rubber material which can wear out or get damaged.

Rear caliper on 2005 Ford F150 not releasing, replaced both rear calipers, now pedal goes to the floor - no brakes at all. What can/should i do?


Sounds like it still has some air in the system or a bad master cylinder. First try bleeding all air, there is definitely some air left in the lines and this is most probably causing the problem. Bled the lines at the bleeder screws on the calipers. ---------- There is air left in the brake line.Any time the brake system is opened to replace brake lines, caliper, pads etc etc.Mostly the air enters the system, and that air has to be completely bleed.Otherwise the same symptoms , what you are getting will be noticed.-------- Brakes can be bled manually, with a power bleeder, injector tool or vacuum bleeder.IIt does not make any difference which method you use as long as all the lines and components are flushed with enough fluid to remove any trapped air bubbles or air pockets.----
The most common bleeding procedure is to bleed the brake furthest from the master cylinder first, then bleed the other brake that shares the same hydraulic circuit (which may be the other rear brake on a rear-wheel drive car or truck, or the opposite front brake on a front-wheel drive car or minivan). After these have been bled, you then bleed the other brake circuit starting with the furthest brake from the master cylinder.--------- When the complete air is bleed from the line, the brake should be firm when car is on.In your case brake brake pedal is loose and goes almost to the floor when car is ON.This is due to Air in the line.Get the complete air bleed from brake line.------- This will help.Thanks.Helpmech

Good question, on the antilock system is a bleader too and bleade it the same way you bleade the caliper. After all is done adjust the rear brakes, they should have a drag to them.

Spongy brake pedal on 2003 Frod escort zx2.


loosen of the hand-brake adjustment and press the brake pedal a few times to self adjust the rear brakes.
Re-tighten the handbrake adj last.
Front brake sounds like a seized caliper,If possible remove caliper and clean and lubricate the piston.
This may work but replacement caliper may be the only other solution.Make sure the caliper slides are also clean and lubricated and the brake pads are in good order.(TRY THIS FIRST)
Also new brake shoes can make the pedal feel spongy for a couple of hundred miles until they have been run in.

When you bleed the brakes are you starting with brake furthest from the master cylinder? Also was the master cylinder bench bled? If everything there is okay and you are not getting any air in fluid stream, you could try bleeding the brakes by having some one slowly pump the pedal till it is firm. Then have them let off open first bleeder valve and slowly depress to floor and hold there untol the valve is closed. repeat this at all bleeders. You may want to have car running to do this. Try this and let me know.

Emerg. Brake Drum Removel on E450 .


The park/emerg. brakes should be integrated with the rear brake rotors. To replace them involves removing the calipers and brackets. You should be able to slide the rotors off. You may have to back the park brake shoes off with the shoe adjusters to remove the rotors due to the rust lip that often develops within, but they should slide off once freed. Hope this helps.
