My issue is very little braking power. I have added fluid, and blead out the system. However, I still have very little in the way of brakes. Once I cram the pedal down to the floor it will stop but just think they should work better. I am curious if this issue sounds like a brake booster issue. I do know the truck has new rear brakes, and when I blead the front calipers the pads looked to be at least 50%. Due to my bleeding of the system, all dark colored fluid was flushed and only clear remains.
this may be a silly question, but it sounds like you still have some air in there...did you bleed them in order from the furthest to the closest wheel from the fluid reservoir?...if you do them randomly you can sometimes just chase an air bubble around and it won't get out.
Well....I did not follow that Operating Procedure. I am going off of memory as it has been some time ago and I am just now posting in a fresh thread. I do remember when we replaced the rear shoes the rear brake cylinders were spewing quite a bit of fluid. I think I rationalized it to myself that all the air was out of them.....probably a dumb idea. How would you suggest to blead the rear brakes, I do not remember them having bleed valves.
your rears have bleed screws on them unless they were broken off....unlikely but possible...make sure all the front and rear bleeder screws aren't seized...just wd40 them a few days before you work on it to be sure they will free up ..starting with the wheel furthest from the reservoir,pump and bleed as you normally would (or if you have a vacuum bleeder thats the easiest)then the next furthest away,the last one should always be closest to the reservoir..good luck
yup, air - bad! had a car that was doing that, bled the heck out of the front brakes cause they were new calipers.. turned out to be some air trapped in the line to the rears!
Hallo there! I have the same spongy brake problem. Got my front calipers rebuilt. Drained the brake system (just happened while calipers were being rebuilt). Then I bled the lines, starting at the back, then passenger, then driver. Still have spongy brakes! Takes about 3 pumps of the brake pedal to get pressure. Do i need to bleed more? A mechanic told me I may need to bleed something called the master cylinder. . . Also - there only seems to be a bleeder valve on ONE of the back drum brakes. The other is not broken off, it just has another brake line where the bleeder is located on the other drum brake.
Try a vacuum bleeder, or a pressure bleeder. But, for the cost of those tools, you may be able to hire someone to do it. My local ATV shop will work on my Hijet if I ask them to, and they have no issue with it’s “strangeness”.
