Really? Still with the brakes.

Post by danboy282 »

Well, i have changed everything but the booster, rear hose, and metal lines. Front brakes were still building too much pressure. When checking and re-checking everything,i re-measured the brake booster push-rod that goes to the master cylinder with a digital caliper (unavailable to me before) and found it to be out too much (+1.00"). My repair manual says it shouldn't be more than .995" from the master cylinder mounting surface.

After adjusting the push-rod in properly and test driving, the brake pedal has a ton of travel before I get any braking action. There is no more pressure build up... finally. Call me crazy I get a little nervous when i go to hit the brakes and they go half-way to the floor before starting to slow me down.

So the question I have is... did having the push-rod out too far damage my brand new master cylinder thus causing my problem?

Any help greatly appreciated

You probably just took the rod in to far. you might have to adjust it a couple of times to get it right. adjust it back up to where u dont have slack but not so.much that it puts pressure on the master cylinder.
