Looking for some suggestions. '02 EX with lots of miles. When I apply the brakes somewhat aggressively the car pulls left for a split second then straightens out. Don't notice it when lightly applying the brakes. About a year and a half ago it got all new brake lines, pedal does not feel soft or squishy at all. I originally thought the front right caliper was sticking, taking time to apply. Caught it dragging one day so I replaced it, no change. Could this just be caused by different calipers on left/right?
Front left isn't in the best shape but it doesn't drag. Front right is about a month old, brand new part. I can't make sense of why an old caliper would grab quicker than a brand new one unless it was dragging (which it isn't).
Was the new one an OEM one? Maybe they are valved or internally sized slightly different?
Both are OEM replacements. Front left is a Power Stop reman about 6 years old. Front right is a new (not reman) Raybestos unit. Please note I felt no change after replacing the front right caliper.

This issue has finally gotten on my nerves after about a year. I'm thinking the master cylinder is faulty. The car utilizes a diagonally split brake system (one hydraulic circuit for FL and RR, another for FR and RL), the master cylinder applies pressure to both circuits. If something were bad in the master I could see how it would not be applying equal pressure to both lines simultaneously. I replaced the master two years ago with a Centric brand, issue started about a year afterwards. I think I'm just going to replace the master with an ACDelco or Raybestos brand, both have good warranties.
I don't have the tools to properly diagnose this issue (nor do I plan on buying them), so parts cannon it is.
Ordered a new master cylinder on Rockauto. Paid for the cheap USPS shipping, estimated delivery date of 5/10. Randomly got it in the mail yesterday so replaced it tonight. Wife was helping me bleed the brakes and said she hated the front right because it was harder to push the brake. Well that's not a good sign.
I'm sure it was happening when we replaced that caliper and she just didn't say anything. Only bled that corner so she had nothing to compare it to. So somewhere that line is partially blocked. Next up, brake hoses. They've never been replaced in the car's 300k+ miles. Any other suggestions?
I was going to suggest replacing the brake hose as it may have a weak area that is bulging. But you already came up with that idea so...
No change with a new master cylinder huh?
Went for a test drive after, first time I used the brakes I could still feel the pull. I did check the hoses for bulging but didn't see anything. I think there must be something stuck inside.

I have thought that as well but the issue happened with the old caliper as too. No issues with the old caliper until some point after I replaced all the hard brake lines. Brake hoses will be ordered today, we'll see in a week or so.
Ordered both front brake hoses from Rockauto on Wednesday, 5/5. USPS delivered them 5/8, about a week ahead of the estimated arrival date Rockauto provided. Rockauto/USPS has been kicking butt recently. Anyways, pulled off the front right brake hose and tried to blow through it but could not. We got it boys. Installed both front brake hoses and went for a test drive, braking is perfectly centered now. Appreciate all the input!
