Brembo brake problems - do they need to be bled?

I am having intermittent issues with the brakes being 'squishy' on my brembo package car. Most of the time when I drive it, the brake pedal is difficult to modulate and the amount of travel is inconsistent. It feels squishy and the brakes seem to come on really suddenly, so it's hard to have a smooth stop. Other times I will get into the car and the pedal is stiff and applies pressure sooner, like I would expect it to do.

Has anyone else had similar issues? Should I take it to the dealer?

Stainless steel lines won't flex so they may eliminate your issue if you're willing to mod the brakes

While the SS lines would improve brake feel, it shouldn't be inconsistent like that with the stock lines. My brakes have always been smooth and predictable so far in the first 2300 miles. I would probably take it in and have it looked at. Could be a problem and you don't want to screw around with a brake problem and end up with no brakes when something fails completely.

Have the brakes bled and pressure tested, then see what it's like. Sounds like air in the system to me.

I probably will but since I live about 10 miles outside of Washington, DC, I can't trust anyone to touch my car. I only ever bring cars in to a shop as a last resort. The quality of people in general around here just freaking sucks. Can't wait to move somewhere else. It is like living in a third world country.

Just as an example, I had a BMW X3 that was serviced under warranty because of a hard shifting automatic trans. After the first trip, the car came back with a drive-shaft out of balance and the whole car would shake randomly. Had to drop the car off, they claimed they couldn't reproduce it. Came in, had the issue reproduced in about 1 minute of driving, and they fixed it. Picked the car up and the steering wheel was now on crooked. I have had similar terrible experiences with Honda dealers, one resulting in my 2008 Accord being bought back under lemon law.

Plus I wanted to see if anyone else had similar probs. I kinda want to bleed and put in DOT4 fluid anyways....already have a motive bleeder, just need the adapter.

brake bleeding

You need to electronically bleed your brakes. You have to do this before you bleed them the old fashioned way. Bring it to Ford to have it done right or find a shop with some up to date computer equipment and ABS diagnostics tools.

Alright, I'll take it in. What do they need to do with it electronically?

I'd like to respectfully disagree with Entrenched. If you have a Motiv bleeder, then bleed the brakes with it. If that doesn't fix the problem, then take it to a dealer to have the ABS/DSC pump bled. But do it yourself first - I would.

Also, I used to use Castrol SRF fluid in my BMW but I'm using the Motorcraft branded fluid (DOT3) in the Mustang for track days. The temp ratings are not that different, and the Ford fluid is cheaper.

Well I brought it in, and as expected, the techs said they think the brakes feel fine. Utter ********. I have a Honda CR-V and the brakes in that are much more responsive and solid feeling. I've owned an E55 AMG, BMW 3-series, X3, Supra, all had better, firmer brakes. There is no friggin way this brembo package is supposed to feel like this.

Guess I'll buy the adapter to my motive bleeder.

Get a friend to help. I own three pressure bleeders and I still get a family member to push the pedal when I want it absolutely done right.

The Brembo package is solid. I put in Goodridge lines recently and its easier to modulate, but the truth is that even with the standard hoses, it's really good.
