Mushy Brakes (Read 3717 times)

Hey guys,

I finally got around to bleeding the brakes and the pedal is still mushy as ever and the pedal goes all the way to the floor. The brake warning light does work. I used a 1 man bleeder and a good bit of air came out of each valve. I do know that the reservoir for the rear got dry but I pumped 3 bottles of fluid thru the system. Haven't tried bleeding the master cylinder so I'll try that tinight if I can get one of my kids away from the TV for a minute. I also have a broken bleeder valve in one of the calipers. It's the drivers side rear inboard. can I get all the air out with just the outboard bleeder or do I need to drill and re-tap? This is the only thing keeping me from getting it inspected and I'd really like to have a valid sticker on it not to mention being able to stop in the rain. Any suggestions would be greatly appreciated.

Charlie

If the M/C got dry it needs to be redone again.. You will also have to drill & tap to get all the air out of the rear caliper.

The passengers side has one of those bleeder repair kits on it and I got one out of the help section. gonna try an easy out first and maybe I'll get lucky and not have to do it but in case it goes bad, I have the repair kit on stand by. Just have to buy a 21/64 bit and a 1/4" NIP tap. I went to 5 stores looking for the drill bit and tap but nada.  but the day I goose chasd for the brake hose, Oriely had stock and the bit and tap so now it's just a matter of doing it.

Had the same problem with mine a two years ago, I had to bleed the master cylinder to make sure all the air was removed. Once this was done I redid the wheel cylinders again going from passengers side in side to outside then to the drivers and so forth. Remember there are two bleeders per caliper. I tried to tap the bleeders out and ended up replacing the caliper, hope you have better luck than I did.

I think that is the best way to go. Wink  Extremely hard to tap out the bleeder and get it right. Sad

Well, I tried an easy out which broke off into the drilled out bleeder. took forever to chisel it out without wollering out the hole. Bought my drill bit and tap and had new threads in about 15 min. couldn;t believe how easy and smooth it went. would have done this the instant I say the broken bleeder if I had known this. installed the base and then the new bleeder valve and was finally able to get all of the air out of the rear. Finally it stops! I need to do the front again just to make sure I got all the air out but what a differeence.

Also since I had the rear end jacked up, I re-positioned the e-brake brackets and now have a good half inch clearance from the tires. I was even able to remove those washers I had on the studs and feel more comfortable that the wheel is now flush with the rotor.

Thanks Ron, by the time it came down to run the 21/64 drill bit, the hole was damn near that size already and a bit larger the 1st few threads but that made it easier to tap. I really lucked out to get er done with no leaks.
