Eric Platford - Chief Quality Engineer} PN.{Mr Northey} OY. (SB{Mr Bull/Mr Bannister}) Exptl. No. 4950 REF. Hsl/LG3. 2. 26. OBJECT OF TEST. To prevent mud getting on to front brakes. TESTER A.J.Lidsey. CONDITIONS. Road tests on 9-G-111. SUMMARY OF TEST. On the 10,000 miles test on 4-wheel brakes on 20 HP. it was found that considerable quantities of mud got on to the brakes. The effect of mud getting on to the brakes is to increase wear, cause squeaks and effect the co-efficient of friction of the material. We have recently had a Barkers Trials 20 HP. car returned to the Works with bad front brake jaggers. This fault was caused by the effectiveness of the front brakes being considerably increased due to the dried mud on the braking surfaces. The fault disappeared after the brakes had been cleaned. As the modification to overcome this complaint is very simple, we recommend it is standardised at once. Hs.{Lord Ernest Hives - Chair} | ||
