I've been having a few issues with the Nissan's braking.
They didn't seem as sharp as usual and there was a continuous irritating rubbing noise from them. Don't get me wrong they were still better than the MG's brakes!
Initially I decided to change the brake fluid as it hadn't been renewed for 5-6 years, and give the system a good bleed.
There was an improvement, but not great.
I slipped up to my mate's MOT station and got the car on the brake tester. Verdict, the brakes wers good enough to pass an MOT but there was a 20% imbalance on the front brakes.
The brake setup is the same style as the standard MG setup.i.e. A fixed calliper carrier and a floating single piston calliper.
Usually, the problem is that the sliding pins seize over time.
I stripped the brakes, and indeed, the bottom pin was partially seized on the nearside, and the bottom one on the offside was
completely solid!
I also found the reason for the rubbing noise.
