My brakes keep binding up I think its just my front brakes but it might be all four..



I tried bleeding the brakes, then I rebuilt the calipers, Then some more bleeding! There still draging a bit and getting pads and rotors pretty hot....



What could it be..???? The master cyl..??? mine is pretty new. I have new ss brake lines, calipers, pad's, master cyl..??? what is up with this thing...???? https://www.nopistons.com/forums/pub...1047683561.gif

well I bought all the bake parts at the same time, But I know it can't t it's not the sbe the pads. I just rebuilt the calipers. I trust that it's not the new stainless brake lines. ...



So I'm thinking about replacing the master cyl.. I mean what else could it be.?? The proportioning valve..???? https://www.nopistons.com/forums/pub...1047683561.gif

the porportioning valve could be stuck, but that would affect the rear brakes only.. are the fronts sticking too?



wich ones are getting hotter? front or rear?

The fronts get by far the hottest out of the four.. so the valve isnt the problem..??? I think victorya Brittish sold me a crappy master cyl.. Most of the rubber parts i have got from them turned out to be ****... my new ball joints tore the boots in 2 mounths same for the boot on the slave cyl i got from them.....

Oh I have had that problem before. Mine was the shaft that goes from the master cylinder to the pedal. try re-adjusting that

I would start with bleeding the ENTIRE system. If there is any moisture in the lines it can lock up pretty easy. I noticed that you mentioned that you had bled the brakes already but did you flush the entire system?



Then I would move to the proportioning valve.



You said that the calipers are new? If they are new then I would try other things first before I replaced those. How do your lines look?

Well I found out that the auto parts store sold me the wrong caliper grease.. They sold me some "CRC Synthetic brake & caliper grease"



After I rebuilt the calipers I was reading ALL the print on the back and it says "not to be used on internal piston calipers" Damn!!!



So it's my fault I should of read the back of the bottle. So I ordered 2 more rebuild kits and bought the right grease, The "ultra synthetic brake & caliper grease"



So I'm going to rebuild the fronts again (The right way) Then bleed the entire system and try again..... https://www.nopistons.com/forums/pub...1047683664.gif



Edit: Oh yeah good idea about the adjusting rod for the master cyl.. I'm going to back it off a bit.

Hey, at least you found the problem https://www.nopistons.com/forums/pub...IR#>/smile.gif

I hope thats all thats wrong.. Because they were binding before I rebuilt them.

if that doesnt fix it, next step would be to loosen a brake line at the master, if it doesnt fix it, its between the master and the wheel, if it does its the master....
