1997 Bentley Brooklands — MOT failures & pass rate
The 1997 Bentley Brooklands passed 88.4% of its 387 recorded MOT tests. Against all cars of a similar age (25.0% fail rate), the 1997 Brooklands comes out 13.4pp better. Failures cluster in brakes, lighting & signalling and suspension.
What the MOT record shows
No single area dominates — brakes (7.0%) and lighting & signalling (4.1%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are rbt (sp), headlamp aim and washers — rbt (sp) alone was recorded 18 times.
Mileage matters less than usual here: the 1997 Brooklands fails 8.7% of the time in the 30-60k band and 6.7% at 120-150k, a spread of only 2.0 points.
Suspension is the most common advisory, noted on 17.8% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 16.1% in 2021 to 8.6% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 1997 Brooklands
The failure pattern for this year is specific enough to inspect against: brakes accounted for 7.0% of tests. Start there.
- Brakes (7.0% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Lighting & signalling (4.1% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (4.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
