Chapter 8 Wheels and Tyres

Greg Hudock Brooklands Books ePub

Tyre pressures and the condition of the tyres should be checked once a week. Remember that the tyre is the only contact with the road surface.

Inspect the tyre walls for cracks, splits or bad damage. If the tyres are worn on one side, in most cases on the outside, check the front wheel alignment. Normally the toe-in setting will need adjustment.

Excessive wear on both sides of the tyre indicates driving with an under-inflated tyre. Excessive wear in the centre of the tread indicates an over-inflated tyre.

Damage can also be caused by sharp objects or contact with kerb stones. A clear tread pattern should always be visible.

Do not drive with tyres if the depth of the tread is less than 1.6 mm (0.06 in.).

Check the tyre pressures once a week in accordance with the figures given in your Owners Manual and on a sticker attached to the vehicle. If the tyres lose more than 2 psi. per week, then the tyre has a puncture or the seal on the wheel rim is damaged. Take the faulty wheel to a tyre specialist. Always keep the valve caps in place as these will prevent leakage of air from the valves. Do not forget to replace them after you have checked the tyre pressures.

Chapter 6: Brakes

Andrew Everett Brooklands Books ePub

The braking system on the E30 is pretty straightforward. 316, 316i, 318i and 320i cars without ABS use a disc front and drum rear set up, whilst all other cars use rear discs. 316, 316i and 318i cars used solid front discs with ventilated front discs for everything else. It is the usual split hydraulic system with the usual problems relating to old age but it is not hard to work on. Some cars will have ABS and that can be problematical in old age with many an owner driven to drink by the flashing orange ABS light on the dashboard.

First things first brake fluid should be changed every year. Brake fluid is hygroscopic which means it absorbs moisture. This can gather inside the fluid reservoir and once there is moisture in the fluid it will not show up until the brakes are used hard and get really hot. The water will boil and evaporate leaving air locks in the hydraulic circuit and not much of a reaction from the brake pedal. Synthetic brake fluids will go a long way to curing this, but so will renewing the fluid every year with conventional mineral based fluids.

Chapter 5 - The Initial Purchase

Gordon Lund Brooklands Books ePub

What to Look For

You will probably have an idea already on which Elan you prefer. If you want to carry children as well as adults then the Elan +2 will be your target. The same applies if you have a limited budget but want the Elan experience. Remember though that the saving will only be on the initial purchase. Most other costs will remain the same. Early +2s are usually cheaper than +2 S130s and 5-speed models.

Two-seater, or baby Elans as they are often now called, command a higher price because of their popularity and scarcity. Some have been written off, some have been exported overseas, mainly to Japan and the ones that remain are treasured possessions that people are loath to part with, even if the car is a wreck. So finding a restoration example is not going to be easy. There are cars out there for sale but the trick is finding one suitable for restoration at the right price.

The final choice may not be yours at all but finding something close that meets other criteria better. S1 and S2 Elans are rare and command high prices. S3s and S4 Elans are more prolific, the SE versions again commanding a premium. Further up market is the Elan Sprint and finally, drop-head versions of all models command higher values.
