New mustang, Brake problems/questions.

Alright guys I need your awesome help I just bought my gf a 2003 mustang v6 and it has a brake problem, we got it for 4600 with 85k miles on it btw.

The problem: When you push on the brakes it seems hard, and like the power braking isn't helping, then it will all the sudden kick in and make it much easier to stop and works much much better. Could it be a master cylinoid? Or however you spell that. Help out please

If it was the master cylinoid it'd go straight to the floor. What I'd do is do a complete brake tune up (new fluid, pads, check the calipers & rotors, rebleed, ect.) I'm not exactly sure but that's my input. Good luck with it

Maybe check the brake booster and the vacuum lines for it

Yeah I was reading and it sounds like the brake booster is going bad.

Yeah a service would probably fix it. Could be air?

I was thinking air too or maybe you just have to lube the slide pins

Re: New mustang, Brake problems/questions.

At this point, I would also replace the front brake hoses when you do a service.

I just bought a pair for my car, The cheapest ones I found were at O'Rileys for like $17 each. Probably cheaper somewhere else.

Over time they can swell on the inside and act like a check valve, only allowing fluid to travel in one direction. My left front brake drags because it can't release the pressure. This leads to excessive and uneven pad and rotor wear, and most importantly, unstable braking (which is what I am just beginning to experiencing).

$17 each is cheap insurance compared to a new rotor and pads.

Just my 2 cents...
