Brake hoses are an important part of the brake system .They face immense pressure from the brake fluid and also have to survive the harsh environment.
I chose to replace all brake hoses under preventative care as I notice chaffing of the external hose surface .
Method :
1. The customary jacking up of car and placement of jack stands with rear wheel chocks; douse all the bolts with penetrating fluid WD40 at start of the entire process to sufficiently help in removing the bolts
2. Wash with diesel,soap and water and WD40 all the parts of the hoses which need removal to prevent contamination of the closed system
3. The hose needs disconnection at 3 areas; from the steel brake piping, a bracket on the knuckle and from the brake caliper.
4. I strongly recommend to get a set of flare nut wrench as they are very useful to remove the delicate bolts and the bleeder screw without rounding of the edges.
5. There are 2 E-rings /clips for retention of the hose on the wheel well and knuckle which are easily removed by prying with a screwdriver or use a curved cutting plier.
6. First , break lose the bolts at the steel pipe end and caliper end to be sure they can be removed .
7. Next undo the E-rings.
8. Now undo the 10 mm screw at the upper end of the steel brake pipe where it meets the flexible hose .Insert the plastic cap at the mouth of the screw to prevent loss of brake fluid .Use a tray at the bottom to catch excess fluid leaking.
9. Then remove the hose from the knuckle bracket
10. Undo the 14 mm Banjo bolt holding the caliper end of the flexible hose pipe .
11. Clean the areas with fresh brake fluid only and not anything else so as to contaminate the system
12. Now start assembly from the caliper end; loosely attach the banjo bolt with new crush washers.
13. Align and fix the E-ring at the knuckle bracket and finally screw-in the nut at the upper end at steel pipe with hand.
14. Take care to not cross thread either at the steel pipe end or the banjo bolt end ;use your tactile sensation to feel the threads entering smoothly .
15. Now tighten the 10 mm screw with the flare nut wrench snuggly and the caliper end Banjo bolt to 23Nm.
16. Undo the 10 mm bleeder screw and now do gravity bleeding to allow fluid through the new hose .
17. Top up the master cylinder with fresh brake fluid and perform brake bleeding to ensure proper brake function .
18. Take the car in slow speeds and ensure braking quality is adequate .Also rinse areas with spilled brake fluid with soapy water as it can corrode paint .
