I picked up a used master and brake booster from a DA and installed them in my crx yesterday. I drove it around a bit and the brakes felt awesome so I got on the highway and went to my friend's house. Once I exited I could smell my pads smoking so I took it slow to my friend's a couple blocks away. The pedal also felt very hard. I left it there overnight and towed it back.

I figured the pushrod in my booster had to be off so I took it out and it was slightly according to the manual. I adjusted it a little shorter than the specs and put everything back in. I jacked the front up and rev'd the engine a bit and sure enough the front brakes started gradually seizing up again.

I tried loosening the brake lines to the master and once I did that the calipers would release. The back brakes do not seize and the booster holds vacuum.

Anyone know whats going on? I figure I have to get a new master but want to be sure that will fix it.

I have stock brakes front and rear, and stainless lines.

 

What type of brakes do you have on the front? are they integra 10.5 or civic STD/HF?

 

sounds like the master cylinder...

 

were u sure to bench bleed before you threw all that together.

Stock crx dx.

And yes it was bench bled.

 

I had the same problem after i installed my dc mc and booster. I changed my calipers cause i thought they were seize, cause i bough them off a DA at the junk yards. After bleeding it alot of times it was stilll the same but when I changed the brakes lines it went away.

 

You mean the hard lines?

 

I didn't have that problem when I got the DA MC & BB, but after a few months I upgraded to Teg brakes.

The rubber lines coming from the hard to the caliper. The problem with mines was that one caliper was always locked but right after I swap the lines it released.

 

Sorry for the OT, but anyone wanna clue me in on this "bench bleeding" process?

I'm also about to do a DA MC/BB and Knuckle/brake swap.

 

Oh..both front brakes are locking on mine, it must be the master.

 

You hook two lines back into the resevoir, fill it up with fluid and pump away til you're no longer pumping air.

 

Awsome...did you take that pic for me?

 

Of course I did sweetheart

Actually I was gonna do brief write up about installing this thing but I had this problem.

 

Ahh IC. I would have had to commend you if you did, not that I can't commend you now though...

 

So what eventually turned out to be the problem? I am currently having the same issue with my brakes.

 

I replaced the master cylinder and it worked fine.
