Distributor Insertion Techniques

Normally insertion of the Distributor is quite straightforward if you remember the angle you withdrew in the first place in exactly the same position when you withdrew it and provided the crankshaft had not been turned or disturbed since the last time you took the distributor off the cylinder head.
If the crankshaft pulley has been turned for whatever reason after the distributor had already been removed earlier, then it is imperative that you need to get the correct timing before inserting the distributor back into its fold.
The picture below can summarize quite a lot in terms of the explanation that entails with it :

Power Window Diagnosis and Methodology

Power Window Switch

Power Windows problems are usually caused by oxidation in the joints as do many electrical connects but shorting to ground is also common. A basic understanding of the circuitry is important and the best approach is using a test pen to pin point by back probing the connectors with the ign on , the ground pins and the live pins.
Test pen can be used to test ground or live as follows:

Brake Bleeding

 

Brake Wheel Cylinder

Brake bleeding must be performed whenever the brake pedal felt 'spongy' or any brake components are replaced, for example, brake shoes, brake pads, brake calliper pistons, brake wheel cylinders or every 50,000 km or 5 years or more.  Vehicles that are 5 years or more will have brake fluid heavily contaminated and the water absorbed in the brake fluid will corrode the brake wheel cylinders, the brake piston chambers etc.. Brake bleeding at the rear wheels normally will show a highly contaminated brown fluid oozing out of the brake nipple.
