I have a 2008 Mazda 3 TS D. It's my first car, so I'm still unsure as to what is normal and what is not. I'm in the UK (Northern Ireland).
It recently (Saturday) passed it's MOT, but the parking/brake efficiency on the MOT certificate are as follows:
- Service Brake 61%
- Parking Brake 23%
Also, the following brake imbalance results:
- SB. Axle 1 -> N/S: 2.91 -> O/S: 2.57 (Brake Force (KN)) -> 12 (Brake Imbalance (%))
- SB. Axle 2 -> N/S: 1.79 -> O/S: 1.68 (Brake Force (KN)) -> 6 (Brake Imbalance (%))
- PB. Axle 2 -> N/S: 1.74 -> O/S: 1.57 -> Nothing under brake imbalance
I had a full service done before the MOT (by Kwik Fit) and took all of their advice (including adding new brake pads). It was a bit pricey! It feels like these numbers should be a bit higher.
Do the above numbers look OK, or should I be expecting a bit better after quite a lot of (expensive) work after a full service?
