Brakes Pull to the Right Options

[bkrantz]

Some of you might remember my struggle to get what I considered strong braking, even after many rounds of bleeding, bedding, pad brand changes, and voodoo. I finally noticed how much the firewall flexed and the master cylinder moved under hard pedal pressure, and built a brace to support it. See my main thread.

On my first drive of 2023, the brakes finally felt strong, and I could lock up the front pretty easily. But with strong brake response I now have strong pull to the right.

I did set the rear pad clearance on both sides, inside and out, to .004".

Any suggestions?

One thing I have not done yet is corner weight balance. If the right front (and left rear) are carrying too much weight, would that make the car pull to the right as the weight shifts forward under hard braking?

You might want to flush the fluid and bleed them again.
Might be something wonky in the fluid that expands or contracts based on temps

I was struggling with brake drag on a Volvo and I learned a new thing (for me)
The piston retracts only from the force of just the rubber boot wanting to go back to its natural state.
That is not a lot of force.
Admittedly it only needs to retract a mm or two

But, if there is any dirt, rust, particles, it can (and does) easily get stuck
Brake fluid attracts water
These cars sit around tons more than our daily drivers
An annual brake flush might become a thing for me.

I will say, I bought the vacuum brake tool that sucks the fluid through, and that makes the whole process much simpler.
